Nearly $60 million in jewelry. This is what Christie’s auction of Magnificent Jewels in New York totaled. To be precise, total sales are $58.8 million, with 93% sold per lot and 105% sold above the low estimate. The top lot was a 31.62-carat fancy blue diamond, the largest ever to appear at auction, which sold for $11.8 million. In short, diamonds as an investment are always interesting. Other pieces that earned a six-figure rating include an 86.64-carat diamond pendant necklace that sold for $5.7 million and a 107.46-carat large fancy yellow diamond brooch by Graff that sold for 2.6 million, while an important diamond ring of 51.60 carats was purchased for 2.5 million by the prince of dealers William Goldberg.

Fancy Vivid Pink Diamond di 13,15 carati

Year 2022 is the year of pink. Christie’s, in fact, is offering a new pink diamond at auction which, according to estimates, could be sold for up to 35 million dollars, with a minimum estimate of 25 million. The diamond is considered one of the finest fancy vivid pink emerald-cut diamonds ever offered at auction and will be part of the Magnificent Jewels sale December 6 at Rockefeller Center in New York during Luxury Week.

The Fancy Vivid Pink Diamond is prong set in a ring and has impressive VVS1 clarity, weighing 13.15 carats. A pink diamond of this size and quality is rare. In the fancy vivid pink range, a diamond over 6 carats is rarely encountered and less than 10% of pink diamonds weigh more than a fifth of a carat. The Fancy Vivid Pink Diamond is therefore considered one of the most important colored diamonds to appear on the market. The Winston Pink Legacy (18.936 carats) surpassed 50 million in 2018 and set a world record price per carat for a pink diamond sold at auction.

Sotheby’s has put the turbo. The great auction house continues to present exceptional stones. This time the news comes from Dubai, where Sotheby’s showed one of the largest diamonds, called The Golden Canary. It is a 303.10 carat “monster”, and is the largest flawless or internally flawless diamond ever graded by the Gia. In short, an exceptional stone even if the price will probably remain lower than those of pink or blue diamonds. Estimates for The Golden Canary point to around $ 15 million. The stone will be auctioned at Sotheby’s New York in December. Curiously, it will be offered without reserve with bids starting at just one dollar.

We have had a bumper year in which we have featured stunning colored diamonds at our global jewelry auctions, as the demand and appetite for these rarities continues to grow. Just two weeks after the record sale of the Williamson Pink Star for $ 57.7 million, we are honored to offer the largest polished diamond in existence to appear at auction. Steeped in history, The Golden Canary is one of the most exquisite diamonds ever discovered, not only for its size and intensity of color, but for its extraordinary beauty that is sure to fascinate collectors around the world. Sotheby’s has the privilege of helping write the next chapter of this incomparable and reborn gem.

However, The Golden Canary remains an exceptional stone: it has been classified as a Fancy Deep Brownish-Yellow Diamond. The gem also has a story to tell. It was cut from a giant 407-carat rough diamond with a shield shape. The Golden Canary was consequently cut into a pear shape. The diamond will be presented on a world tour. After Dubail, I will be in Taipei, Geneva and Hong Kong.

The fair jewels of Brilliant Earth

Published on October 17, 2022

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.

Anello in oro giallo e diamante taglio brillante

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).

What is a cubic zirconia?

Published on October 12, 2022

da sapere

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.

Anello in metallo placcato con cubic zirconia by Stroili

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.

Anello in argento placcato oro e cubic zirconia — Anello in argento e cubic zirconia di PdPaola

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.

Anello a fascia placcato oro rosa con cubic zirconia di Bronzallure

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.

The pink diamond challenge: Williamson Pink Star sold for 57 million

Williamson Pink Star è montato su un anello diamanti taglio trapezio e rosa taglio brillante

A pink diamond breaks all records. The sample is the Williamson Pink Star, an 11.15 carat vivid fancy pink diamond. The stone was sold in Hong Kong by Sotheby’s for over 57 million, exceeding the presale estimates, which had prudently stopped at 21 million dollars. However, it was not a Chinese tycoon who bought the precious diamond, but a billionaire from Florida. As is tradition, the new owner has changed the name of the gem, which is now called The Rosenberg Williamson Pink Star.

The diamond was extracted from the Williamson mine in Tanzania and then cut by Diacore. It was also the second largest vivid pink diamond ever to appear at auction, later, the CTF Pink Star, which weighs 59.6 carats and was bought in 2017 by Hong Kong group Chow Tai Fook for 71.2 million: it is the most expensive gem ever sold at auction. Soon after, however, is the Williamson Pink Star, with a price per carat of around 5.2 million, double the previous record of 2.7 million per carat of the 18.96-carat Winston Pink sold by Christie’s in 2018. .

How long will the new record last? On November 8th, in Geneva, Christie’s will sell another 18.18-carat pear-shaped fancy diamond, called The Fortune Pink: pre-sale estimates indicate a value between 25 million and 35 million dollars. The race is underway.

What are laboratory diamonds?

Published on October 8, 2022

news

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.

Synthesis diamond con taglio a pera, pietra creata in laboratorio

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.

Un impianto di produzione di diamanti sintetici

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).

Controllo del reattore al plasma CVD che produce diamanti in laboratorio di De Beers

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.

Punto luce di Lightbox — Punto luce con diamante di laboratorio Lightbox

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.

Diamante di laboratorio del peso di 2 carati, venduto da Lightbox per 1850 euro

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.

Features
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.

From Christie’s an 18.18 carat pink diamond that brings good luck

Published on September 27, 2022

news

It is called The Fortune Pink. Could it be because it brings good luck, or because whoever can buy it for sure has had a lot of luck in life? The doubt is destined to remain, also because it is foreseeable that the future buyer of The Fortune Pink will remain anonymous. The gem will be auctioned by Christie’s next December in Geneva. It is a diamond with exceptional characteristics: pear-shaped fancy vivid pink and unusual dimensions for a diamond of this type: it weighs 18.18 carats. And for this it is the largest pear-shaped fancy vivid pink ever put up for auction. The diamond will be the most prized piece of the Magnificent Jewels sale: it is valued between 25 and 35 million dollars.

After The Rock, a 228-carat diamond sold this May in Geneva, Christie’s is proud to present The Fortune Pink, the largest pear-shaped fancy vivid pink diamond up for auction. With its auspicious weight of 18.18 carats, this exceptional pink diamond with a phenomenal color is sure to bring luck to its new owner.
Rahul Kadakia, Christie’s International Head of Jewelery

The name of the diamond comes from an interpretation in Chinese. The number that indicates the carats, in fact, can be interpreted as a good omen of prosperity in the Mandarin language. The largest vivid pink diamond sold by Christie’s so far has been the 18.96-carat Winston Pink Legacy, which reached 50 million Swiss francs, a world record. Fortune Pink will be shown in New York on the week of October 3, before touring Shanghai, Taiwan and Singapore. The diamond will then be exhibited to the public during Christie’s Luxury Week at the Four Seasons Hotel des Bergues in Geneva from 2 to 8 November.

Rare stones, refined cuts, tradition and innovation: all this is Harshad Ajoomal, Mumbai’s jeweler ♦ ︎

The briolette cut, with its elongated teardrop shape, is back in fashion in jewelery. This was renewed by Harshad Ajoomal, a Mumbai jeweler who used this form born in the Sixties, which says inspired by the traditional Indian Goswala cut. When gemstones have a briolette cut and are exposed to strong light, each facet reflects the color to create a sparkling kaleidoscope effect. An effect that the Indian designer has applied in the Mozambique collection, dedicated to a country that holds in its mines a great variety of precious stones.

Jealous of Indian tradition and culture, Harshad Ajoomal used this form for the capsule collection made with natural precious stones such as sapphires, tanzanites, peridots and orange amethysts. But also unusual stones, like Namibia pietersite. Harshad Ajoomal, in fact, has always emphasized avant-garde design, precious stones and craftsmanship. It is an Indian brand, but very attentive to the world of Western fashion, as is also evident in the Mozambique collection.

Williamson Pink Star, diamante rosa di 11 carati

An 11-carat pink diamond is a very rare gem. For this reason, the auction by Sotheby’s to be held in Hong Kong on 5 October is a special event also in terms of price: the diamond, which has been called Williamson Pink Star, is valued at over 20 million dollars. It will be sold at a single lot auction. Williamson Pink Star is the result, after cutting, of a diamond that was originally a 32-carat rough stone found in the Williamson mine in Mwadui, Tanzania. It is a mine that has already supplied diamonds with this rare color.

Diacore purchased the diamond for $ 13.8 million, approximately 427,000 per carat, from the mining company Petra Diamonds in December 2021. The diamond was subsequently cushion-cut and mounted on an 18-karat gold ring, flanked by trapezoid cut diamonds and brilliant cut rose. The gemstone is of impeccable quality and, according to Sotheby’s, is the second largest fancy vivid pink diamond ever to appear at auction, after the 59.60-carat CTF Pink Star, purchased by Chow Tai Fook of China for 71.2 million. dollars in April 2017.

Who buys laboratory diamonds?

Un diamante grezzo emerge dal reattore al plasma CVD di De Beers

Who buys factory-made diamonds? Synthetic diamonds, from a chemical point of view completely identical to natural ones, are a recent bet on the jewelry market. While until a few years ago these diamonds, produced with different methods, were confined for industrial use (for example, for cutting machines), now artificial diamonds are also more widespread in jewelry. Those who sell them define these stones as “grown” or “grown” in the laboratory. Pay attention to it: the two terms, chosen for marketing, suggest that the stones are like plants that grow or are cultivated in a kind of greenhouse. An idea that has thus been associated with the concept of sustainability: the diamonds that come out of a production plant are green, those extracted from the earth are not. An idea that does not all agree with. Certainly, however, they are cheaper diamonds.

In any case, marketing and advertising are powerful tools, as certified by a market research conducted in the United States by The MVEye. The research identified the buyer groups who, according to the analyst firm, are driving explosive global growth in the lab-grown diamond industry. The company has divided the customers of these synthetic diamonds into several groups. The first group is defined as In the Know (i.e. informed) and is made up of millennials between the ages of 25 and 38. In short, young people who have established that laboratory diamonds are truly green. The group, the survey specifies, includes multiple ethnic groups and non-traditional couples.

Orecchini con diamanti di laboratorio Lightbox di De Beers

The second group, on the contrary, has been described as In the Dark (that is, they are in the dark). This segment of people is also made up of millennials between the ages of 25 and 38 who, however, have not heard of lab-grown diamonds. On the other hand, according to The MVEye they can easily be persuaded to buy synthetic diamond jewelry. This group also includes multiple ethnicities and non-traditional couples.

The third group detected is that of Upgraders (ie those who like to update themselves on news). They are more mature consumers, aged 55 or over, but ready to buy engagement rings (if they are sprightly) or more easily for some anniversary. They often don’t have much knowledge about lab-grown diamonds, but they might be motivated to buy a larger size diamond if they find that man-made ones are cheaper. In short, it is a question of budget. Finally, another group has been defined as SPF, which stands for Self-purchasing females, that is, women who buy jewelry for themselves. According to the research, they too would be a type of customer ready to buy an artificial diamond thanks to the price advantage.

One of the most exclusive jewelery brands in the world is Chatila. The Maison was founded in 1860 and has remained a family-run business, with the founder’s grandchildren actively involved in the day-to-day running of the company. Chatila works in between Geneva and London but, in reality, the jewels are designed in Italy and Paris, even if the gems are then mounted on the final jewel by the craftsmen of the house. If you are looking for a Chatila boutique, try the most luxury shopping streets: there are showrooms in the most prestigious streets, such as Rue du Rhône in Geneva, Old Bond Street in London and Madison Avenue in New York.

The history of the Maison, however, does not begin in London, but in Birut, where the founder, George Chatila, opened his shop. It is now the third and fourth generation, Nicholas Chatila and his children, Marwan, Edward and Carlos, who own the business and continue in the footsteps of the founder. In 1983 the company moved to Switzerland. Today a flagship Chatila showroom on Rue du Rhône in Geneva, while the other main one is located in London’s Old Bond Street. A new showroom was opened in Riyadh in 2003 and another, in Doha in 2014.

Chatila’s specialty is super diamonds. It was among the first, among other things, to use large colored diamonds. Moreover, one of the few red diamonds in the world is by Chatila, The Flame of Argyle. All family members take part in the selection and evaluation process of unique and rare precious stones. An example of rarity is the ring with a 4.29 carat radiant cut chamaleon diamond. The definition of chamaleon refers to the fact that it is a very rare diamond with shades that change according to the intensity of the light that hits it. Also the person who will decides to buy it will probably change color when he will knows the price.

The new uncompromising geometries of Etho Maria, a maison that combines ceramic and diamonds ♦

Born in the home of philosophy, Athens, Etho Maria has chosen the philosophy of luxury with a bit of surprise. The Maison, which from Greece soon expanded to the rest of Europe and the USA, is anchored to the idea of jewelery with much geometry. Not by chance Euclid and Archimedes was not Greek. Geometry, but precious. And surprising. Like when Etho Maria presented a collection that combines red ceramic with sparkling white diamonds. No doubt a combination that has remained in the memory. The idea, among other things, has earned awards such as the Diamond Classic at the Centurion Design Awards 2018 and the Editor’s Choice at the 2017 Centurion Design Awards in Scottsdale, Arizona.

In addition to red ceramics, the Maison has also decided to use the ceramic-diamond pair also with other colors, like white. The effect always works. Alongside this series of jewels that use an innovative aesthetic to an equally refined goldsmith technique, the Maison offers more traditional jewels, but always with a design that does not forget the modern style which, for example, does not omit stones cut with the shape of the triangle. Jewels that have been chosen by luxury chains, such as Neiman Marcus or Saks Fifth Avenue for ad hoc sales.

Mindi Mond describes herself as a devoted wife and mother and a dedicated board member of the Thanc Foundation (Thyroid, Head and Neck Cancer). But she is better known, however, as the founder and designer of the Maison that bears her name. He lives and works in New York, but his jewels seem more inspired by the ancient (and also modern) Art Deco. In fact, Mondi says that his mother was a collector of vintage jewelry, including those from the Victorian and Edwardian era.

A passion that reverberates on the collections that the designer offers: for example, jewels can be made with elements of ancient rings, necklaces, earrings, bracelets or watches dismantled and adapted according to the taste of Mindi. But not only of course. They are classy jewels, in 18 or 14 carat gold, but also silver, diamonds, and sometimes colored stones, such as rubellite. Diamonds are the most used stone by the designer, in particular with different cuts mounted on the same jewel.

Diamrusa, a Thai brand specializing in precious stones and high-end jewelery ♦ ︎
Yes, India is the country with the greatest consumption of gold and the jewelery has a ancient tradition. But there is no doubt that nearby Thailand occupies a prominent place for its factories where precious stones and jewels, often of the highest quality, are worked. There are many European Maison that entrust the making of high jewelery, in whole or in part, to the laboratories where expert and skilled Thai artisans work. And so, after all, it is not surprising that one of the companies that partly produce third parties was founded by an Indian diamond dealer, Salil Shah.

In addition to buying and selling stones, in 1986 Salil Shah founded Diamrusa. It is not strange, however, that he chose the country of Southeast Asia, since in Thailand the trader also has been living for over 30 years and where, among other things, he devotes much of his free time to a charity organization engaged in various social awareness activities. Diamrusa is a manufacturer of high-end jewelery. In addition to diamonds, it effortlessly uses rubies, emeralds, sapphires in partly traditional designs, partly oriental for Asian markets. At the Swiss city fair, for example, he exhibited three large impact rings made with traditional gemstones surrounded by pear-cut diamonds.

Pear-shaped diamond rings

da sapere

Do you want to buy a diamond ring? Consider the idea of a diamond with pear cut. Here’s what to know before choosing a diamond with pear cut ♦

Usually the classic diamond ring has a brilliant cut stone. That is, with a perfectly round cut. Another variant is the princess cut, which has the advantage of minimizing the scraps resulting from diamond cutting. But if you like a slightly less used, less conventional form, you could choose the diamond pear-cut.

How to wear diamond pear cut

The pear cut is a mixture between a marquise cut, as an eye shape, and a brilliant cut. The drop shape, if it is mounted on a ring, should preferably be worn with the point pointed to the nail, because it makes the fingers look more slender.

The pear cut diamond is six hundred years old

This particular diamond cut was created by Lodewyk van Berquem, Belgium, in the early 1400s. Van Berquem has been an innovator in diamond cutting technology and has also introduced new ways of polishing: some of his innovations are still used today.

The shape of the pear diamond

The pear cut diamond uses 71 or 58 triangle-shaped facets, depending on the size, weight, and type of stone. It is not easy to cut a diamond with this shape, also because this type of shape involves a lot of waste. Also for this reason the jewels that use a pear-shaped diamond are quite rare compared to more common cuts.

Why choose a pear cut

Although it is more difficult to cut, pear shape has some advantages. For example, with the arrangement of the facets, any inclusions may be more difficult to detect. Conversely, in diamonds with less facets such as Asscher or Emerald Cut, inclusions are much more visible. Pear cutting also offers a benefit to those who wear it, since it tends to make your fingers more tapered.

How to choose a pear diamond

It must be perfectly symmetrical.
The tip should not be rounded.
Let it rotate under the light: it must not have “black spots”, that is, without reflections.
Read carefully the certificate of the gemmological institute that evaluated the stone. An identical for a quality stone should have these characteristics: good cut, color H, clarity: SI1, 56-70% percentage depth, table 53-62%, length-width ratio 1.45-1.70.

Few and incredible: the jewels of Saboo

Strepitosi, refined, complicated: the exclusive jewels (40 per year) of Saboo Fine Jewels ♦ ︎
In India, the city of Jaipur, in Rajasthan, is also the capital of jewelry for its tradition in the processing of gems. There are many jewelry companies that cut and assemble precious stones. But few are those able to embed the gems one inside the other, with complicated, delicate and very difficult joints. As you know, for example, Saboo Fine Jewels. La Maison has become famous, among other things, precisely because of its processing capacity, which sometimes touches the unthinkable.

The company’s history began in the 1930s, with Chand Bihari Saboo. From the business of gems the company founded by Saboo has evolved and in 1980, his sons, Rajendra and Surendra, formed Saboo Fine Jewels. Which, however, now is based in Hong Kong. Even in the Chinese city, however, they have not lost contact with the world of precious stones. Indeed, Saboo Fine Jewels is famous for the choice of gems, as well as for their processing. But not only: for some jewels, for example, it uses the conch pearls, among the rarest and most expensive. A pearl conch is the fruit of a non-pearly calcareous concretion produced by the Queen Conch mollusk. They have a pinkish color, with different shades.

Given, however, that the jewels of Saboo are the top of the top and, above all, difficult to manufacture, the Maison manages to produce only 40 per year. The last frontier is the use of colored titanium, light metal, resistant, but very difficult to work with. To create a pin, a unique piece made to measure, for example, a half year of work is been needed, between the search for stones, the special cut and the goldsmith’s art. And what is more precious than time?

Another diamond for collectors is ready to challenge the Magnificent Jewels auction in New York, on June 8, as part of Christie’s Luxury Week. The diamond, like all special gems, also has a name: The Light of Africa Diamond. The estimate ranges from 11 to 18 million dollars. The Light of Africa is a flawless D color (best) emerald cut diamond of 103.49 carats with excellent polishing and symmetry. It also belongs to the rare type IIa category, which makes up less than 2% of all diamonds, making it one of the rarest and most precious gems.

The diamond has been classified by the Gemological Institute of America and is accompanied by a report by Gia which emphasizes its classification as the apex of the diamond pyramid. The gem was cut from a rough stone of 299.3 carats, unearthed from the Cullinan diamond mine owned by Petra Diamonds. The large gemstone was mined, cut and polished in South Africa. The Cullinan diamond mine has produced some of the most historic diamonds, including the Great Star of Africa and the Second Star of Africa, both of which are part of the British Crown Jewels set in the Scepter of the Sovereign and the Crown of the Imperial State. The Light of Africa Diamond will be presented at Christie’s in Geneva from 6 to 11 May, followed by a tour of Christie’s Hong Kong from 22 to 24 May, before returning to Christie’s New York and will be exhibited from 3 to 7 June.

The diamond weighs 15.10 carats, which corresponds exactly to 3.02 grams. This gem was sold by Sotheby’s, with a price that even exceeded the pre-sale estimate, which was 48 million.
