Are Lab Diamonds Like Teslas?





Is it fair to compare synthetic diamonds to Tesla cars? Is a gem produced by a carbon-containing gas factory really green? And do synthetic diamonds have a sustainability license? These are questions that follow an interview with a promotional flavor by Forbes (find it here) to Anthony Tsang, CEO of The Future Rocks, a new online market for jewels created by various designers, which uses so-called laboratory-grown diamonds, i.e. artificially produced. The company is based in Hong Kong and seeks customers among the youngest, Millennials and Gen-Z, i.e. in their twenties and thirties. According to market research, this age group is the most sensitive to the issue of sustainability.

Furthermore, as is known, laboratory diamonds are also less expensive than natural ones. But it is the green aspect that is underlined by those who sell them. In reality, the sustainability of man-made gems is only relative. Lab-grown diamonds are produced in two ways: with reactors that use a high-pressure, high-temperature process or with a chemical process that consists of carbon vapor deposition. “We don’t compare with natural diamonds, we just provide different option, the market is big enough,” Tsang said. Okay. But the manager goes further: “Fifteen years ago everyone laughed at Tesla and now Ferrari is also entering the electric vehicle market”.

This comparison, however, does not seem entirely apt. First of all, electric cars are not green products: they consume a lot of generally non-renewable energy, and the construction of their huge batteries requires excavations and land devastation to extract the so-called rare earths. Furthermore, looking forward these batteries will constitute a huge management problem at the end of their life cycle. In addition to costing more, electric cars also require an infrastructure that has yet to be built to bring the electricity needed for recharging everywhere. This means thousands of kilometers of copper cables, which will cause a huge extraction of ore in addition to the energy consumption necessary to create millions of points needed for recharging. Therefore, Teslas and electric cars in general are not really green products. But the sustainability of electric cars is not the point. Does this hammering marketing on the alleged green aspects of synthetic diamonds make sense? Wouldn’t it be better to just say that factory-created gems cost less and have the same chemical property, though not the allure, as earth-created diamonds?

For Recarlo luxury in yellow




Luxury is not just white. Recarlo is the Italian brand that more than others has conquered the jewelery stage with its jewels in white gold and colorless diamonds, albeit with some sporadic expansion to blue sapphires. Now, however, the Valencian company adds a new color to its offer: the fancy yellow diamond. The Maison has introduced a line dedicated exclusively to yellow diamonds. They are particularly refined high-quality jewels that are positioned in the top price range.

Recarlo points out that in nature only one diamond out of 10,000 can be defined as fancy. Precisely for this reason, colored diamonds are also considered a form of investment and reach stratospheric prices at auctions. The diamonds in this case are used for a series of solitaire rings with different shapes and carats, but always with gems weighing more than 1 carat. The prongs used to stop the diamond have the particularity of being in yellow gold, to give continuity to the setting, while the rest of the setting is in white gold. The diamonds are offered in different cuts: navette, cushion, drop and oval, which emphasize the color of the gems.

Boucheron rises tenfold at Cambi’s auction




It is not often that a jewel is bought ten times the starting price at an auction. It happened with the bracelet with carrè and brilliant cut diamonds, black enamel, emeralds, rubies and cabochon-cut sapphires signed Boucheron Paris, put up for sale by the Milanese auction house Cambi. The jewel started with an estimate of 35,000 – 45,000 euros, but was sold for 496,000 euros, over the phone, by a buyer from the United States. A sign that at auctions you can find jewels at prices which, at least according to the buyer, are quite undervalued compared to the real value.

Cambi Casa d’Aste concluded three days of auctions which included jewels, coins and wines, divided into six rounds. Total sales amounted to 2,830,000 euros. The Fine Jewels auction, in particular, recorded a turnover of 2,122,000 euros, with 115% of sales by value. Among the other jewels that went to auction, it is worth mentioning the emerald-cut diamond of 4.06 carats, sold for 77,500 euros (from an estimate of 45,000-55,000) and the emerald-cut diamond of 6.21 carats sold for 112,500 euros (estimate 50,000-70,000). Success also for the Numismatics department directed by Paolo Crippa, which totaled 225% sold by value with 90% of lots awarded. The top lot is the gold medal for the 1878 coronation of Umberto I, sold for 39,000 euros.

Harakh high jewelry




Diamonds and not only in the collections of Harakh, a new high jewelery brand ♦ ︎

There is a new high jewelery brand in America. It’s called Harakh and, to tell the truth, it is new only for the United States, because in Bombay they have known it since 2017. The name is that of its founder, Harakh Mehta, who represents the fourth generation of a family of jewelers. But in India the word Harakh also has the meaning of joy: which is also that of those who can afford to buy a jewel of the Maison, which has prices ranging between 20,000 and 100,000 dollars. Among the latest creations of the Maison there is, for example, a set of 150-carat diamonds, specially created to celebrate the 150th anniversary of the Bloomingdales luxury department in New York.

Diamonds are one of the strong points of Harakh’s jewels, also because the activity of a jeweler comes after that of a gemstone merchant, and also thanks to his studies at the Gemological Institute of America. Use only diamonds classified D, E or F and clarity VS / VVS and IF. Each piece is handmade by the 15 artisans who work with ancient jewelery techniques. But this does not prevent a quality control particularly attentive also to the use and pleasure of wearing rings, bracelets and earrings. As in the Cascade collection, which is made with a blaze of stones. The shapes of the jewels are modern, but in some cases they reflect the traditional Indian figures, such as the elephant or the peacock.

Gilberto Cassola, tradition is a flag




The jewels of Gilberto Cassola, Maison of Valenza that has just landed on the 1stdibs platform ♦ ︎

Is it possible, in 2017, to practice the profession of jewelry craftsman, at a high level, without being squeezed between the big brands that offer mass jewelry and famous Maison that enjoy eternal fame? Gilberto Cassola & C, a small company from Valenza, tries to show that there is also a different way to make jewelry. The Gilberto Cassola & Jewelery Factory was founded in 1965 in Valenza (Alessandria, home of Italian high jewelery) by the homonymous jeweler who is still in business, but flanked by his son, Graziano Cassola, who travels the world to offer jewels in gold with diamonds and precious stones of the highest quality and design.

In particular, the Piedmontese Maison seems to specialize in building refined jewels with stone pavé. Which form, in some cases, designs, even those of national flags. The production, as mentioned, remains artisanal, in the laboratory of the Piedmontese town. But the company does not just offer its own pieces: it also works on commission for individual jewels or for entire collections, as well as selling jewels on the 1stdibs online site.

What does Fa Gioielli do with Alliori




Fa Gioielli, from family Alliori to the goals of Valenza tradition combined with the pleasure of innovating ♦

The Alliori family, from Valenza, has two fortunes. The first is to own an excellent company, Fa Gioielli, founded in 1960 on the initiative of Mario Alliori. The second is to have the designer, Alessandra Alliori, who continues the tradition with the Alliori brand collections. Alliori brand jewels are sold in 27 countries around the world, in Europe and in the United States. The jewels are made of 18K red gold, with white or brown diamonds set.

A globetrotting life is to give life to the business of the company, but does not limit creativity, largely modulated around the use of colored precious and semi precious stones, emeralds from the tourmalines, to which are added the classics of the jewelry, that are gold and diamonds. But more Alessandra Alliori seeks to explore new areas of the design of the universe.

The Firmament of Crieri




The firmament, that is the celestial vault – A romantic term to describe what for adtronomists is simply the stellar space. It is also the name used by Crieri for a collection that is inspired by the stars, but with the aim of creating jewels capable of symbolizing a piece of the night sky. The Firmamento collection consists of necklaces, bracelets and rings in the tennis style, which is the specialty of the Piedmontese Maison. The tennis motif, however, is reinterpreted with 18-karat white, pink or burnished gold. The stars that shine are white (on white gold), brown (on pink gold) or black (for burnished gold jewelry) diamonds.

The diamonds are set on the tennis surface by alternating higher carat, brilliant cut gems with other smaller diamonds. The bracelets are available in variants from one to seven strands, in a white gold version with white diamonds, in a pink gold version with brown and white diamonds and in a burnished gold version with contrasting black and white diamonds. The collection includes rings with three, five or seven threads, also in this case with the combination of the color of gold and diamonds. And to admire this firmament, no telescope is needed.

Dezso, Sara Beltrán’s wish




Envy her: Sara Beltrán, spends her time traveling between the sea of ​​Morocco, Mexico, Croatia, Italy and Greece. To rest she can choose between houses in Paris, New York and Jaipur, India. Between one plane and another, he invents jewels for his brand, Dezso. Curiously, the Maison’s website explains the name as a translation of the word desire from the Latin. In reality in Latin the word desire is cupiditatem, while Dezso is a male name in the Hungarian language which means, precisely, Desire. Between one trip and the next it is easy to get confused, probably.

In any case, the designer is from Texas, born in El Paso and raised in Mexico. In this country she has learned to love the sea, a source of inspiration for her jewelry. So much so that he uses shark teeth for some jewelry. Although, in truth, it is a marine species considered in danger of extinction. But, of course, not only shark teeth, but also uncut polki diamonds presented in their natural state, much used centuries ago in India. In short, a mix that reflects the designer’s perpetual motion.

The Starlight Collection by Yoko London




Stars found at the bottom of the sea. This is how South Sea pearls used together with diamonds for the new rings, necklaces and earrings from Yoko London’s Starlight Collection could be considered. The pearls, which are grown in the water of the oceans, become the stars at the center of the jewels inspired by the constellations that illuminate the night sky. And as in the constellations, the collection features some geometric motifs: pearl spheres, symbolizing stars and planets, are found next to the rays that shine from diamonds, often used in diamond patterns.

In addition to the white pearls, the collection also uses the black ones from Tahiti. The rings are offered in the moi et toi version, with pearls alternating with white diamonds. Maison Yoko London specializes in pearl jewelery and has just opened a large store in London. The company was founded in 1973 by the Hakimian family and has chosen to use only natural pearls of the best quality.

The fair jewels of Brilliant Earth





If you have noticed that a competition is underway among jewelers to see who is more respectful of the environment and uses ethical principles in the procurement of gold and gems, know that there are also those who have thought about it before the others. Brilliant Earth, based in San Francisco, sells jewelry and even single gems, natural or laboratory that it guarantees are ethically sourced. And given that over the years the trend of sustainable and environmentally sensitive jewelry has begun to appeal to the general public, in 2021 the company also decided to go public on Wall Street.

Brilliant Earth was founded in 2005 by Beth Gerstein and Eric Grossberg. According to many, the example of the Californian company has prompted many other jewelers to imitate its philosophy. Brilliant Earth uses natural diamonds that come from the Diavik and Ekati mines in Canada, Namibia and Botswana. Sapphires, on the other hand, come from Australia or Malawi. Gold, silver and platinum are either recycled or by cooperatives that meet the standards set by the Alliance for Responsible Mining. In addition, they are Certified Carbonfree Business Partners and use certified sustainable wood for their jewelry packaging boxes as well. Obviously the company is certified by the Responsible Jewelery Council and, as if that were not enough, it uses a blockchain platform to guarantee the traceability of the gems.

The list of good deeds also includes funding a mobile school in Lungudi, Democratic Republic of Congo, and collaboration with Rainforest Alliance, an international non-profit organization. Oh, yeah, what about the jewels? They are quite traditional. Through the website it is also possible to create a ring by choosing the type of setting, shape and quality of the diamond. This too is an act of goodness (for those who buy).

L’elenco delle buone azioni comprende anche il finanziamento di una scuola mobile a Lungudi, nella Repubblica Democratica del Congo, e la collaborazione con Rainforest Alliance, un’organizzazione internazionale senza scopo di lucro. Ah, già, e i gioielli? Sono piuttosto tradizionali. Attraverso il sito internet è possibile anche creare un anello scegliendo il tipo di impostazione, forma e qualità del diamante. Anche questo è un atto di bontà (per chi acquista).

The challenge of blue diamonds





Color challenges for diamond enthusiasts (and investors). After the record-breaking pink diamonds, a new auction is expected but centered on a different shade, blue. This time it is Sotheby’s to present a group of eight fancy blue diamonds, which have been valued in total over 70 million dollars. Diamonds will be the protagonists of several Magnificent Jewels auctions, this winter and next spring. The name given to these gems, The De Beers Exceptional Blue Collection, indicates their origin: the company specializing in “women-friendly” stones.

The eight diamonds have different shapes and weights: they include an oval brilliant cut diamond of 1.22 carats, one step cut of 11.29 carats, for a total weight of 32.09 carats between them. Three diamonds will be offered this year: a 5.53-carat fancy blue at auction scheduled in Geneva on November 9, a 3.24-carat diamond and a 2.08-carat diamond in New York on December 7th. De Beers and Diacore paid a total of $ 40.36 million for five rough blue diamonds from the Cullinan mine weighing 85.62 carats in November 2020. In nearly two years, Diacore has cut and polished the five rough stones to create the eight blue diamonds from the collection that Sotheby’s now presents.
The valuation of diamonds of this type is quite difficult. Suffice it to say that the 11.29 has an estimate of between 28 and 50 million dollars.

What is a cubic zirconia?




Cubic zirconia: This stone is often used in jewelry. But few know what cubic zirconia really is. For example, what is a cubic zirconia made of? Is it very different from a diamond? What are the differences? The answers are known to (almost everyone) those who deal with jewelry. But, if you are reading this article, it is because you want to know exactly what are the characteristics of a cubic zirconia that, perhaps, is mounted on a ring or a pair of earrings that you are wearing.

Beware of the definition
Before explaining what a cubic zirconia really is, we need to clear up a misunderstanding. Often jewelry companies offer rings, necklaces, earrings or bracelets “with zircons”. Well, know that in 99.9% of cases it is not true. In fact, zircon is a rather rare and expensive natural stone (read also: Diamonds or cubic zirconia?). A cubic zirconia, on the other hand, is an artificial stone. So, be careful when you read that a piece of jewelry is composed of cubic zirconia, it is probably not true. Pay attention to it: those who use this marketing ploy propose fake “zircons” with metals such as steel or silver, hardly with 18-karat gold. By the way, sometimes cubic zirconia is denoted only by the abbreviation used in chemistry, CZ.

What is a cubic zirconia?
In short, the answer is: it is (almost always) an artificial stone, produced in a factory. Although it looks like a diamond in appearance, a cubic zirconia is composed of zirconium dioxide and not carbon like natural gemstones. In fact, microscopic grains of natural cubic zirconia have been identified in nature: they are certainly not those commonly used in jewelry.

What is the difference with laboratory diamonds?
As we have explained, cubic zirconia is made up of zirconium dioxide. Man-made, lab-created diamonds are composed of carbon, like diamonds found in nature. To learn more, read also: What are laboratory diamonds?

What are the characteristics of a cubic zirconia?
The main feature, which is the key to the success of cubic zirconia, is the resemblance to the diamond. But it doesn’t have the same properties. For example, if you look at the bottom surface of a diamond, you can see a rainbow reflection. Cubic zirconia, on the other hand, is limited to an orange and blue reflection due to a different refractive index. When exposed to short wave UV rays a cubic zirconia emits a fluorescence that tends to yellow, greenish yellow or beige. Another feature concerns the hardness. Cubic zirconia is at 8-8.5 on the Mohs scale, so it is a little harder than most natural semi-precious gems, although less than diamond, which is at 10. Yet cubic zirconia is considered brittle, yes breaks easily.

How is cubic zirconia produced?
The most used method is the one called skull fusion. No one is beheaded: it is named for the shape of the crucible used which resembles a skull, surrounded by radio-frequency activated copper coils. It is a system patented by Josep F. Wenckus in 1997: it consists in heating the base material to temperatures of over 3000 degrees. With this method, however, it is difficult to predict the size of the crystals produced and the crystallization process cannot be controlled. To improve the result, several techniques have been introduced, including coating the finished cubic zirconia with a carbon film, similar to diamond, with a process that uses chemical vapor deposition. Or someone vacuum sprays an extremely thin layer of a precious metal (such as gold), which creates an iridescent effect. However, the effect is not lasting. The commercial production of cubic zirconia began in 1976. But it is not the only artificial stone to be used in place of diamonds. In fact, synthetic moissanite, with similar characteristics, has recently become widespread.

How is it different from a diamond?
An expert gemologist can immediately discover the difference between a cobic zirconia and a diamond. For one thing, an artificial stone has no inclusions in it, as often happens with a natural gem. Furthermore, cubic zirconia weighs much more than diamond. It has a density that is approximately 1.7 times that of the natural gem. It is therefore sufficient to compare the weight of two stones of the same size. If you drop the stones in a liquid and compare the descent times you will see that the diamond will sink more slowly than a cubic zirconia, because it is lighter. The refractive index is also different: cubic zirconia has it of 2.15-2.18, compared to 2.42 of the natural gem. Paradoxically, moreover, cubic zirconia is more perfect than a diamond: only very rare natural gems are truly colorless (with a classification D). Most diamonds have a slight tinge of yellow or brown. A cubic zirconia is often completely colorless – equivalent to a diamond’s D. However, there is also colored cubic zirconia.

What are laboratory diamonds?

It has been talked about for years, but many people still don’t have a clear idea of ​​what stones are called lab grown diamonds. If you are looking for a quick and concise description of artificially produced diamonds, here we are. Basically, there are two methods to produce man-made diamonds, but in both cases the gems are identical, from a chemical point of view, to natural stones. But the similarity ends there.

The name of the diamonds
But, first of all, what are these diamonds called? In English the definition lab grown is the most used, especially by the marketing of those who produce or sell these synthetic diamonds. The idea that diamonds grow in the laboratory like tomatoes in a greenhouse offers a greener view of the product. The communication of those who produce and sell them is based precisely on the idea that diamonds created in the laboratory (but in reality they are factories, as for any other product), are more sustainable. Right? Wrong? We see.

Sustainability
A natural diamond, created 2 or 3 billion years ago by the movement of the earth’s crust, is the result of the incredible pressure caused by the shifting of continents. Natural diamonds are therefore found under the ground. To be mined, diamonds must be searched deep or through large excavations in remote areas. Of course this activity, even if it is well controlled today, cannot be defined as sustainable. But, on the other hand, we must not forget that the extraction of natural diamonds also offers a livelihood for thousands of families in poor areas, such as Africa. Finally, any smartphone that you have in your pocket is the result of the extraction from the earth of a large number of minerals and no one is scandalized.

In any case, is it true that lab-created diamonds are green? It depends. First of all, man-made diamonds require an enormous amount of energy to be produced. The vast majority of these diamonds are produced in China and India, but also the United States and Israel, and in many countries, coal-fired plants still represent the predominant source of energy. The emissions caused by the production of lab grown diamonds cannot be considered completely green. Furthermore, few people are needed to produce synthetic diamonds and, therefore, their positive contribution to the social economy is very low.

How are they produced?
Diamonds that come out of a laboratory are produced using two very different methods: CVD (chemical vapor deposition) and HPHT (high pressure at high temperature). Currently the CVD system seems to prevail and, according to some, even offers a better result. So, if you want to buy a jewel with synthetic diamond, you can take the curiosity to ask what type of factory it was produced from. However, both methods use the same basic material: carbon.

The HPHT system
The HPHT process uses a metal catalyst to dissolve the carbon. This process has a disadvantage: a few tiny pieces of metal can enter the diamond and cause visible inclusions. The carbon used, in fact, is pressed inside a metal cube, exposed to immense heat and pressure through electrical impulses. In this way the carbon breaks down and crystallizes in a diamond. But tiny traces of metal inside could make the diamond attracted to a magnet. It sure wouldn’t be nice to buy a diamond ring and then hang it on the fridge door (we’re kidding).

The CVD system
To produce a diamond with the CVD method, a tiny fragment of natural diamond is locked in a machine. Here it is exposed to carbon-rich gas and brought to extremely high temperatures. Within a few weeks, the carbon gas ionizes and the mineral particles stick to the original diamond and then crystallize.

Are laboratory diamonds the same as others?
From a chemical point of view, the diamonds produced in the laboratory are the same as those extracted in a mine. They are, therefore, like any mass-produced object. Natural diamonds, on the other hand, have an unpredictability of color, transparency and size that, obviously, is not present in synthetic diamonds.

Are all synthetic diamonds the same?
No, as with natural ones, synthetic diamonds can also have a different quality. It is only recently, however, that the major institutes have begun to classify them. GIA and IGI, for example, judge them by cut, color and clarity, just like natural diamonds. Excellent cut, D to F color and VS2 to SI1 clarity are the best categories.

How much does a synthetic diamond cost?
The price of a lab-made diamond is determined by many factors. The first is the size, then from the famous 4 Cs that are used to classify all diamonds. Until recently diamond factories were unable to produce large gems, over one and two carats. It is now much more common and quite large diamonds have also been produced. The price, however, is much higher. In any case, lab grown diamonds cost less than natural ones. Over time, however, their price decreases, that of natural diamonds tends to increase.

Laboratory diamonds are as hard and resistant as natural diamonds: they have a rating of 10, which is the highest, on the Mohs scale. Even on a jewel they shine exactly like the others. When buying a diamond jewel can you distinguish if it is natural or synthetic? No, even for a jeweler or gemologist it is impossible to distinguish a natural diamond from an artificial one. However, there are laboratories with special equipment that can identify a diamond created in the laboratory.

Jennifer Lopez’s extremely rare green diamond

/




Green diamonds are very rare and very expensive. Because they have a secret ♦ ︎

Colored diamonds have inflamed Sotheby’s and Christie’s auctions for many years. While colorless diamonds, commonly called white, were once the most expensive gems, now it is the colors that are paid the most. The most popular colors are yellow, pink and blue. Rarer are red diamonds. But there are also diamonds of another color, even rarer: they are the green ones. Extremely rare. One of the few women to have a green diamond in the drawer (but perhaps in the safe) is Jennifer Lopez, who received it as a gift, mounted on a ring.

Because they are green. The green color is extremely rare in diamonds also because it is also believed to be due to the exposure of the stone to radioactive materials. But do not worry: you can wear them without problems. Green diamonds were near, millennia ago, small amounts of material such as uranium or thorium. But over time, radioactivity has declined, that is, it has ceased. In any case, these radiations penetrated the nearby diamond crystal and changed its color.

Artificial green. Since green diamonds are the result of radiation, why not repeat the process in the laboratory? It is, in fact, what some laboratories do to produce a green color in diamonds. The stones are polished and then hit with a low-energy electron beam. With this same system, yellow diamonds are produced. Another method is to apply a thin layer of silica on the surface of the diamonds. But, beware: the coating is very thin and can be lost with normal wear.

The biggest. The diamond called Green Dresden is the largest in the world (40.72 carats) with this shade. It is kept inside the Dresden castle. The ring you see in these images, however, was sold for $ 1.8 million in the spring of 2014. Its assessment is also due to the fact that the jewel is signed by the legendary designer Jar. The colored limestone diamond mounted on the ring weighs 2.49 carats and is set on platinum, surrounded by colorless diamonds. Also interesting to remember the story of this stone: once belonged to Countess Eliza Branicka Krasińska and was mounted on her engagement ring with the romantic poet Count Zygmunt Krasinski, in Poland. The two married in 1843 and remained together until the count’s death in 1859.

Mosaic cocktail with Antonini




There were several extraordinary things that happened in 2022: from reprehensible events, such as the war in Ukraine, to moments of emotion due to the disappearance of great personalities, but also the exciting new images from space, the (almost) end of covid in many areas of the world, enthusiasm for the protection of the environment. In short, the world is extraordinary, for better or for worse. And jewelry can be extraordinary too. Indeed, if we are talking about Antonini Milano, Maison that has made design its flag, we must speak of Extraordinaire, a name that the creative director Sergio Antonini has provided to his line of high jewelry.

2022 sees the addition of two new pieces to the Extraordinaire line. It is a gold Mosaic cocktail ring with the typical satin finish and a concave surface, which is a classic Antonini shape. The upper surface of the ring is composed of a pavé of black diamonds. A pair of earrings with an elongated shape, like lanceolate leaves curved by the wind, is made with the same materials.

The future of laboratory diamonds




As in sport, two teams took to the field in the world of jewelry. The first holds the record in the standings and does not intend to sell it. The second earns points, but is still far from the top. The two rival teams are those of those who use natural diamonds, created by mother nature millions of years ago, and those who produce them artificially with refined machines. The latter are modestly called lab grown diamonds, that is, grown as if they were zucchini in a greenhouse. The reality is different: synthetic diamonds, which are chemically identical to natural ones, are produced with production plants mostly in China and India which are, among other things, quite energy-intensive. But this is another aspect.

It is a fact that with technology it has become easier and cheaper to produce lab grown diamonds. And the question that jewelers are asking themselves, but also many consumers, is whether the sales of these synthetic gems will continue to increase, as has happened in recent years starting from 2018, when the natural diamond producer De Beers also took the field. with the Lightbox brand. Furthermore, a question concerns the natural diamond jewelry market: is it destined to lose market share? These questions are being answered by a specialized analyst, Paul Zimnisky, who has published an analysis reported by the National Jeweler website.
Punto luce di Lightbox
Punto luce con diamante di laboratorio Lightbox

Zimnisky’s analysis is particularly interesting because it looks at the next 10-15 years. The analyst’s first consideration is that, of course, the supply of artificial diamonds is unlimited. Just produce them. And, given the trend, the production of synthetic diamonds should continue to grow to 25 million carats by 2030. A large amount, but much less than natural diamonds, which in 2021 reached 120 million carats. The increase in supply, combined with the often scarce possibility of evaluating synthetic stones, will further lower the price of laboratory diamonds. The analyst gives an example: in mid-2018 a generic 1-carat diamond, G VS1, grown in the laboratory retailed for $ 3,625, compared to $ 6,600 for a natural diamond of the same size and quality. But today, a synthetic diamond of the same size and quality sells for $ 1,615, while the natural equivalent has increased in value to $ 6,705.

He deduces that synthetic diamonds are destined, if the trend is confirmed, to lose value. As opposed to natural ones. But it would be wrong to reduce everything to a question of price. The seller’s brand weighs a lot. Zimnisky takes as an example a brand like Hèrmes: if it sold a good synthetic diamond, it would be perceived first of all as a high-class jewel and then as an unnatural gem. This reasoning leads the analyst to a prediction: most synthetic diamonds will lose value. But there will also be a small number of brands that will be able to use them by leveraging their reputation, as long as they choose very large and excellent quality gems. In short, the synthetic jewelry market could be divided into two classes, normal and premium. The latter may be competitive with natural diamonds but, of course, they will also be more expensive.

A successful example for medium quality synthetic diamonds is, for example, the recent Pandora Brilliance line. But a card to play for manufacturers of artificial gems could be the possibility of personalizing the gems with unusual shapes, an aspect that would allow them to stand out from natural products. The match between the two teams will last a long time.

Yeprem’s Couture jewels




If you still think that wearing jewelry is the same as putting a ring on your finger, wearing earrings, showing off a necklace or surrounding your wrist with a bracelet, you are left behind. The world is running and jewelry is evolving, even the high-end one. Proof of this is Yeprem, a high jewelery Maison that has long since embarked on a new path, as in its Couture line. Alongside traditional jewels, Yeprem proposes compositions of white gold and diamonds that embrace parts of the body with unusual shapes and aesthetic effect. They are defined as “jewels for the hand” in the case of pieces intended to cross the back and appear on the palm.

As for the earrings, even Yeprem has chosen to evolve them into one of the many new shapes that have met the favor of the public. And bracelets are no longer just a circle that is worn at the end of the wrist, but jewels that snake around the arm and hand, with surprising autonomy. The jewels also increase the sensation of movement thanks to the dual choice of diamond cut, brilliant and marquise.

Fortitudo Diamond interactive jewels




Diamonds are forever, at least in your smartphone. The idea of ​​combining emotions and memories with the gem most loved by women is back in vogue on the wings of a start-up that has the privilege of starting not from a garage, but from Via Monte Napoleone, the heart of luxury shopping in Milan. The idea of ​​Fortitudo Diamond, a company founded in 2018 and which developed the innovation called Rem, consists in combining a video or photo recording via an app with the jewel. Bringing the smartphone close to the bracelet or pendant of a necklace, you can see images or sounds previously recorded on the smartphone, for example by the person who gave the jewel. In short, a digital accompanying ticket.

Rem, in fact, is an acronym that stands for Relive Emotional Moments. The idea of ​​the company, which is led by Nicola Rossi, a manager who has an experience with Diamond Love Bond, a company that for a certain period sold diamonds through Ubi Banca, is to increase the emotional impression linked to the purchase. or to the gift of a jewel. Bracelets and necklaces are made of silver or gold, with the addition of semi-precious stones such as opal, malachite or mother of pearl. And, probably, with a tiny RTF chip inside capable of connecting with the Rem app that activates the digital message.

Tiffany ring, mystery setting and trilogy




The three techniques of jewelry that you absolutely must know if you do not want to make bad figures. The first is … ♦

There are jewels that have marked an era. Which have been copied, imitated, and made famous by famous people. In short, milestones in the history of jewelry that you absolutely must know. They are those jewels that have been made with a technique or a form that you must know, if you do not want to make fools. We have selected three of the many jewelery stages.

1 The Tiffany frame

Invented in 1866 by Charles Tiffany and his team of gemologists, it soon became an industrial standard for engagement rings: six platinum spikes (claws) that like claws sprout from the base of the ring and support it in an almost invisible way. to reflect the maximum of light. The traditional alternative, which is still used, is the ring with four jaws. The six brands, however, can be smaller and thinner, so as to bring out the stone and lock it more accurately. Simple, but brilliant.

2 The invisible mystery setting

Patented by Van Cleef & Arperls in 1933, it consists of cutting small parallel grooves along the stone belts downwards and placing them one by one on a gold or platinum net. In practice, it is the gem itself to be inserted into this structure and to hold the nearby stone, with an interlocking game that can be worth even 300 hours of work for a pin. The system is mainly used for rubies and sapphires, while the emerald with its inclusions makes this operation rather risky because it could disintegrate if cut badly. Only in 1990 was this setting developed for diamonds. But today’s advanced techniques with software modeling make this process economically prohibitive, not only for the cost of labor, but also for excessive waste material. Despite this, the mystery setting style is still used by masters of jewelry, such as Jar.

3 The Trilogy ring

In this case it is not a patent or a special technique, but one of the most successful marketing campaigns in the industry: the three diamonds mounted on jaws or set on a faith were certainly not new, but in 1990 De Beers proposed with an advertising campaign created by the American agency JW Thompson. The slogan was: “present, past, future”, declined in about 2000 advertising films and remained in the minds of consumers, so much so that all the jewelers of the wedding segment were pushed to keep a similar model in their catalog.

Quick guide to the cuts of the stones




Quick guide to cuts of stones, diamonds included. Learn to which shape the baguette, marquise, and brilliant cuts match … ♦

Brilliant, marquise, briolette … Diamonds, emeralds or rubies (and all other stones) can be cut in many different ways. But how often do you understand the description of a jewel and do not know exactly the meaning of the different forms that a gem takes on rings or necklaces? Here is a small guide among the different cuts of precious stones.

Baguette. It is a type that became popular during the Art Deco period: in essence, it is a variant of the emerald cut. The baguette, that is the wand, recalls the typical French bread: it is long and rectangular, with octagonal corners and 14 facets. It can create truly amazing effects and adds a strong character to the jewel. But it is also a cut that is not easy to use in jewelry. Baguette cutting is often used together with stones with other shapes. For example, a baguette cut diamond can accompany other gems with different volumes.

Brilliant / Round. The round cut is the most common form for diamonds, also because it enhances the diffraction capacity of the stone, increasing its brightness. The brilliant cut, or round, represents up to 75 percent of the diamonds sold. This cut is quite recent: it was codified only at the beginning of the last century and has 58 facets. The crown is the area that is at the top, the belt is the circumference, the widest. This cut is not easy to make, but it is certainly the one that offers the greatest enhancement of a diamond compared to its weight.

Briolette. The briolette cut is among the best known and is often used to make pendants for necklaces or earrings. This cut essentially has the shape of a drop, but multifaceted. In reality there are four variations of the teardrop shape: the most famous has the facets composed of rhombuses. But there are also the most accentuated drop-shaped, olive-shaped, ball-shaped pendants that take the shape indicated by the name.

Oval. It is a very simple and regular form. For this reason it is commonly believed to be one of the oldest cuts to present a diamond. However, this is not the case: this cut for gems has only been experimented since 1960. An oval-shaped diamond has a uniform and symmetrical design and has 56 facets. Like the marquise cut it is, in essence, a variant of the brilliant cut. The advantage is that the elongated shape makes the stone appear larger than the perfectly circular cut.

Heart. The heart cut is, in essence, a pear shape with an inward fold on the upper side. As it is easy to imagine, it is used to emphasize the romantic aspect, but it is not very easy to make: it usually requires rather large stones and a lot of workmanship. But there are also Maison, like the Italian Recarlo, often use heart-shaped diamonds, even small ones, and have made them a distinctive aspect. For larger stones, however, the heart shape is usually more expensive in proportion to the carats.

Asscher. It assumes its name from Asscher, an Amsterdam company specialized in the diamond trade founded in 1854 by the family of the same name (it is responsible for cutting some of the most famous diamonds in the world, including two of the three largest diamonds ever found). In 1902 Joseph Asscher designed and patented his original Asscher cut of the same name. The idea was to combine the emerald cut with the round cut, in a shape characterized by extreme symmetry and dramatically-cut corners. Like the emerald cut, Asscher needs stones without inclusions and very clear.

Cushion. It is easy to come across the cushion-cut on antique jewelry: it is, in fact, the oldest form, an update of the so-called Old Mine cut of the 18th century. As the name indicates, it is a cushion-shaped cut with 58 facets. The corners are rounded and the facets typically larger than the brilliant cut. But it requires very high-quality stones.

Marquise. Few people know why this form is called like this: according to the legend this cut has instead a spicy story. It would have been invented at the court of the king of France: Louis XIV commissioned it, it seems, to combine the stone with Jeanne Antoinette Poisson, marquise of Pompadour, her lover. The cut is an elongated shape that reaches a point at both ends, with slightly rounded sides. Like the oval cut, the marquise cut enhances the visual impact of the stone, which appears larger than round cuts of the same carat weight.

Pear. Make a mix of the oval cut with the marquise cut and here the result is the pear shape. As the name indicates, the shape is similar to that of the fruit and is widely used in jewelry, also because it has the advantage of enhancing the light in diamonds and adding a hint of asymmetry to the design. A pear cut diamond has 58 facets: asymmetry is one of the most appreciated aspects by many jewelers, who use the pear shape for rings as an alternative to the classic round cut. But this form is also widely used for pendants.

Princess. It is one of the most recent news. In fact, this type of cut has only been introduced in jewelry since 1980 and is very popular especially in North America. The princess cut is square or rectangular, which in some cases manages to be brighter than the typical round cut. But of course it also depends on the starting shape of the stone. Another advantage of the “princess” cut is that it requires less waste of raw stone than other cuts.

Radiant. It combines the virtues of brilliant cut with those of emerald cut. The radiant form was developed in 1977 and has between 62 and 70 facets. It is often confused with the princess cut, but unlike the latter, the radiant shape has cut corners, which slightly sweetens the square shape. With the same weight, compared to a round cut diamond, the radiant surface is 4% smaller. On the other hand, a radiant cut diamond appears larger.

Emerald. The shape is rectangular, with cut corners. It is one of the oldest and one of the most demanding cuts: with this form the defects of a stone can be seen immediately. On some occasions it is also called step-cut, because its concentric, wide and flat surfaces remind the steps of the stairs. Faulty inclusions and colors are enhanced, but at the same time the best stones are enhanced. It typically has 50 to 58 facets.

Trilliant. This cut was also developed by Asscher. It was launched in New York in 1960. It is considered excellent for the ability to enhance light within the stone. Basically it is a triangular shape, with curved and straight parts, sharp and rounded corners. This cut has different variations: the sides, for example, can be curved or straight and the shape of the surface is also subject to different interpretations.
