The highlight of the sale is The Light of Africa Diamond, a diamond that starts with an estimate between 11 and 18 million dollars. It is of color D, flawless, type IIa, emerald cut and has a remarkable weight of 103.49 carats. It is the result of a 299.3 carat rough stone unearthed in the Cullinan mine, which has already produced some of the historic diamonds, such as the two Great Stars of Africa, both of which are part of the British Crown Jewels, set in the Scepter of the Sovereign and in the Crown of the Imperial State.

The sale also includes 12 Jar jewels, which were part of the Ann & Gordon Getty Collection, of which we talked about here. In addition, the auction includes jewels from other important private collections, including a selection of Bulgari jewels from the collection that belonged to the Italian actress Silvana Mangano. Then there are the coral and gold Van Cleef & Arpels jewels from the collection of the socialite Brooke Astor and a pair of emerald and diamond earrings of 13.79 and 12.14 carats owned by a private collector.

A 103-carat diamond for sale in New York




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 second life of Erin Flynn Fine Jewelry




Working for 40 years in the world of finance, between mergers and acquisitions, can be exciting. But in the end she gets tired. Thus, after having worked in several companies and having founded the Vator Investment Club as a business angel, Erin Flynn in 2021 turned the page to devote herself to jewelry, in San Francisco. After, however, having studied the market, Cad design and gained experience from Tiffany and Cartier. The result is Erin Flynn Fine Jewelry. The first collections are called Megawatt, Champagne Bubbles and Defining Lines and are made in the classic three colors of gold with the addition of round or navette cut diamonds.

Rings, earrings and necklaces have simple, minimal shapes, but with a design that adds a defined style to the jewelry. Champagne Bubbles, for example, reproduces the visual effect of bubbles in sparkling wine glasses. The Megawatt line, on the other hand, focuses on alternating between different stone cuts and Defining Lines chooses the path of geometry, with the addition of brooches also for men.

Sotheby’s sells the third most expensive diamond ever: 57.5 million




The 3 most expensive grams in the world: in Hong Kong the De Beers Cullinan Blue Diamond was sold for just under 57.5 million dollars. 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. Yet this is not the record, which belongs to another diamond, the 14.62-carat Oppenheimer Blue, sold for $ 57,541,779 in 2016. It is, however, a minimal difference compared to the entire value. The buyer? He is anonymous and concluded the deal over the phone.

An extraordinary achievement, this diamond is considered to be one of the best De Beers ever seen and we are incredibly proud to join forces with Sotheby’s to share this defining moment in history.

The De Beers Cullinan Blue Diamond therefore became the third most expensive jewel ever sold at auction, behind The Pink Star, which sold for $ 71.2 million in 2017, also at Sotheby’s Hong Kong, and The Oppenheimer Blue. The diamond beaten in Hong Kong was mined at the famous Cullinan mine in South Africa in 2021 and was carved from a rough stone of 39.34 carats.

Two big diamonds and princely tiaras at Christie’s auction




The catalog is now completed. And for fans of exceptional jewelry and gem collectors, who are a particularly popular type of investment in difficult historical times, Christie’s sale of Magnifxicent Jewels on May 11 at the Four Seasons Hotel des Bergues will offer plenty of opportunities. Starting with The Rock, a diamond that starts from one with a very wide gap: from 19 to 30 million Swiss francs (13-24 million euros or 9.2-20.5 million dollars). The diamond weighs 228.31 carats and is the largest ever seen at auction.

We are delighted to present the Geneva Magnificent Jewels auction led by THE ROCK, the largest ever white diamond to be offered at auction and a landmark moment in the market. Alongside this the legendary Red Cross Diamond, which has supported those enduring hardships since it was sold at Christie’s Red Cross Appeal in 1918, is offered with a share of the proceeds to be donated to the International Committee of the Red Cross. With the very best quality gemstones, jewels from noble provenance and iconic designs, the auction represents an exciting opportunity for our international collectors this season.
Max Fawcett, Head of Department, Jewelery

As we have already told, The Red Cross Diamond is back for the third time at auction, which despite its name is a cushion-cut intense yellow color of over 205 carats. It was first sold by Christie’s in 1918, and part of the proceeds went to the Red Cross. And this sale also partly benefits the International Committee of the Red Cross.

For nearly half a century, our family has had the privilege of safeguarding the Red Cross diamond. Since it was first brought to market in 1918, the legacy of this symbol of humanity has always been the support of communities ravaged by war, famine and other hardships endured by people across the world. At this auspicious moment in history, we honour the call others have made before us. In collaboration with Christie’s, we are pleased to offer The Red Cross Diamond for sale with a share of the proceeds to be donated to the great institution whose name it bears. We further dedicate this sale to the tireless efforts of the volunteers of the International Committee of the Red Cross and are privileged to support their cause.

The Magnificent Jewels auction also includes 19th and 20th century tiaras, including the Tiara Fürstenberg (estimate 400,000-600,000 Swiss francs), and a pearl and diamond tiara with the brand of the famous Austrian jeweler Gustav Flach. This exemplary handcrafted jewel belonged to her Royal Highness of her Princess of Fürstenberg, born Countess Irma of Schönborn Buchheim (1867-1948), member of one of the most eminent aristocratic families of the Habsburg Empire. A letter in the Fürstenberg archives, directed by jeweler Flach Mediansky & Paltscho, explains the many ways the tiara can be transformed, from a tiara for Viennese high society court dances to a more moderate style with pearls, while the diamond motifs can be worn as a necklace, brooch or hairpins.

The large yellow diamond of the Red Cross is on sale




A yellow diamond for the Red Cross. In times marked by wars and casualties, support for organizations involved in victim assistance becomes essential: this is why Christie’s announces the sale on 11 May in Geneva of a huge cushion-shaped intense fancy yellow diamond of 205.07 carats. The assessment was not disclosed. Part of the proceeds from the sale will go to the International Committee of the Red Cross.

This is the third time in over a century that Christie’s has presented this large canary yellow diamond of 205.07 carats. It’s a very special bond and a huge honor. Part of the proceeds from the sale will benefit the International Committee of the Red Cross, for a cause that is even more touching in the midst of current affairs.
François Curiel, president of Christie’s Europe and Head of the Luxury Department

The history of the diamond is interesting: the original gem was mined in 1901 in a South African mine in De Beers and is said to have weighed around 375 carats. In addition to ranking among the largest diamonds in the world, a striking feature of the stone is its pavilion, which is faceted in the shape of a Maltese cross. On April 10, 1918, the stone was first put on sale at Christie’s London by the Diamond Syndicate again in aid of the British Red Cross Society and the Order of St John. At the time the entire sale had raised £ 50,000 (equivalent to around 3 million today) and The Red Cross Diamond, the highest lot in the auction, had been sold for £ 10,000 (around 600,000 today), which was bought by the famous London company SJ Phillips. It should be added that colored diamonds were not as popular at the time as they are today.
On November 21, 1973, the same diamond was put up for sale once again at Christie’s in Geneva, this time reaching 1.8 million francs and returning to private ownership. It is now being offered for the third time by Christie’s in 104 years, and will presumably fetch a significantly higher price.







The 6 rings by Jennifer Lopez

//




Jennifer Lopez‘s engagement rings: she has collected six. The most valuable is … ♦ ︎

Is there anything better than a wedding with the man you love? The answer is yes: six engagements are better accompanied by as many precious rings. Or, at least, this is the answer that Jennifer Lopez could give you, who has just announced her new official engagement, with its large diamond ring. Probably JLo is a collector of rings and the rotation of husbands and boyfriends is perhaps due to her desire to get new jewels as a gift.

Jennifer Lopez’s sixth engagement ring, thanks to the comeback of Ben Affleck, was designed and made by Tamara Rahaminov and Nicol Goldfiner, of Rahaminov Diamonds, Los Angeles. The ring has a special diamond: an 8.5-carat natural green gem, set with a white diamond and, surprisingly, on a silver band rather than white gold. Although the choice was probably not made to save money. Green is apparently also JLo’s favorite color. The value? There are those who have estimated the cost of diamonds up to 10 million dollars, because green diamonds are rare and precious but, probably, they cost less. Relatively less, of course.

The previous ring received by the American singer from her ex-boyfriend Alex Rodriguez was instead an emerald-cut diamond of 10-15 carats, with a value of up to 5 million.

L'anello con diamante di Jennifer Lopez
L’anello con diamante per Jennifer Lopez di Alex Rodriguez

The stone that she had given Alez Rodriguez has an emerald cut and the jewel is in Art Deco style. Perhaps not by chance it is very similar to that received by Meghan Markle, the Duchess of Sussex who has considerable popularity (even if the critics are not lacking). In any case, in her first 53 years (which turns on July 24, 2022) JLo received six engagement rings, all of which cost at least six figures.

One of her most precious rings was Harry Winston’s pink diamond that Ben Affleck had previously given her. But the third last ring, also by Harry Winston but this time with an 8.5 carat blue diamond, was very precious: it was estimated that it cost 4 million dollars. It didn’t do much good, though.

L'anello con diamante di Jennifer Lopez
L’anello con diamante per Jennifer Lopez di Alex Rodriguez

La pietra che aveva regalato Alez Rodriguez ha un taglio smeraldo e il gioiello è in stile Art Dèco. Forse non a caso è molto simile a quello ricevuto da Meghan Markle, la Duchessa del Sussex che ha una notevole popolarità (anche se i critici non mancano). In ogni caso, nei suoi primi 53 anni (che compie il 24 luglio 2022) JLo ha ricevuto sei anelli di fidanzamento, tutti costati almeno sei cifre.

Uno degli anelli più preziosi è stato il diamante rosa di Harry Winston che le aveva regalato in precedenza Ben Affleck. Ma anche il terzultimo anello, sempre di Harry Winston ma questa volta con un diamante blu di 8,5 carati, era molto prezioso: è stato stimato che sia costato 4 milioni di dollari. Non è servito a molto, però.

The Rock, the record diamond auctioned by Christie’s




The one referred to as The Rock announces itself as one of the most precious diamonds put up for auction. Christie’s will put it on sale in Geneva on 11 May. Those interested, start saving some money: The Rock is estimated to be between 20 and 30 million dollars. A considerable fluctuation, in any case. It is a 228.31-carat pear-shaped diamond that will be the star at the auction of Magnificent Jewels, as part of Christie’s Luxury Week. It is an exceptionally rare gem mined and polished in South Africa over two decades ago and is the largest white diamond ever to appear at auction.

The Rock will join the very best of legendary gemstones which have passed through Christie’s global salerooms since 1766. The market for diamonds is particularly vibrant and we are confident that this sensational gemstone will capture the attention of collectors across the globe this Spring season.

Classified by the Gemmological Institute of America as G color, VS1 clarity, The Rock is also accompanied by a letter from Gia stating that it is the largest existing DZ color pear-shaped diamond ever classified by the laboratory. The previous auction record for the largest white diamond was a 163.41-carat gem, which was sold at Christie’s in Geneva in November 2017 for $ 33.7 million.

The Rock will be presented at Christie’s Dubai from March 26-29, before a tour of Taipei and Rockefeller Plaza in New York from April 29 to May 1. Finally, it will be exhibited to the public during Christie’s Luxury Week at the Four Seasons Hotel des Bergues in Geneva from 6 to 11 May.

Pure Inspiration for Crieri

/




Minimalist, essential and, perhaps also for this reason, precious jewels. The intention of Crieri, Maison di Valenza (Italy), is deduced from the name of the Pura collection: that is, without frills. Only gold and diamonds in the most classic of jewelry proposals in sync with the season in which the greatest number of engagements and weddings are concentrated. At the center of the Pura collection is, of course, the diamond ring, the solitaire, intended to pair with the lucky one who receives it (or if she buys it alone). Furthermore, in the earrings and pendants signed Pura, the diamond is of considerable weight and size: 0.30 carats, with brilliant, navette, oval or emerald cut.

The setting of the stones is equally classic, with four prongs that use the traditional colors of gold: white, yellow and pink, again at 18 karat. The full pavé ring frames the main stone with brilliant cut diamonds, which completely cover the body of the jewel for a total carat weight of 0.75 carats. Crieri jewels are found in about 250 jewelers in Italy and abroad.

How to change the ring

/




Do you want to modify your engagement ring? Ideas and suggestions ♦ ︎

There are many reasons that can lead a woman to change or modify the engagement ring. If you are interested in changing your engagement ring, here are some useful tips that are worth knowing. In this article you will find the answers to your questions on how and when (and if) to change the ring you received at the time of the promise of marriage.

Recarlo, anello della collezione Blue Carpet indossato
Recarlo, anello della collezione Blue Carpet indossato

Usually, those who want to change the engagement ring have two reasons: the breakdown of the relationship with the boyfriend or husband (therefore: new life, new ring), or the desire to change the shape of the ring, which no longer likes (or maybe she never liked it). This is the case, for example, of the engagement rings that are part of the family inheritance. His grandmother might have liked the ring, and she gave it to you convinced that you would jump for joy. But you don’t like it at all. You may not have had the courage to say it right away, but now the time has come: so how do you change the shape of a ring?

Anello con diamante a taglio marquise
Anello con diamante a taglio marquise

Pay attention to the value

Before going ahead, you need to know one important thing: by removing the ring you have on your finger or in the drawer, its value could decrease a lot. For example, the single value of the diamond and the gold band of a solitaire, when they are separated, is less than the whole ring. So, if you want to disassemble a ring to sell the diamond, know that you will get a price lower than the value of the whole ring. At that point it is therefore more convenient to sell the ring as it is now and buy a new one. The same goes, even more, for period jewels: if they are broken down their value decreases a lot. If, on the other hand, a part of the jewel is damaged, the solution could be to look for a new setting (or a new stone) and reassemble the jewel.

Increase the value

Of course, there is also the opposite aspect. Maybe you have a ring that has an inexpensive stone mounted and you want to replace it with a better gem, perhaps a beautiful diamond. Obviously in this case the value of the ring, after the change, will be greater than what you have now. But be careful to really choose the right stone: a thin metal circle may be too small to hold a large opal. Or, conversely, if the gold band is quite thick, a tiny diamond is in danger of disappearing.

Ring with diamond

If you want to change the diamond of a ring, or add one where it wasn’t there before, it is good that the stone you buy is accompanied by a gemological certificate that describes its quality and carat. If you do not have the certificate (and this is not good) you must obtain a report from a specialized laboratory: only in this way will you be able to know what the real value of the diamond is.

Read also: How to choose a diamond

If you have finally decided to modify your ring, at this point all that remains is to contact a jeweler to create a new ring, naturally asking what the cost will be first. However, you should go to a jeweler with clear ideas: knowing which shape, type and maximum cost to face is a good starting point. Not only that: if you do not have a jeweler in whom you have blind faith, it is better to ask for a quote from at least three different jewelers before making a choice.

Anello di fidanzamento indossato assieme alla fede matrimoniale

Some ideas to transform your ring

1 If you have a ring with only one diamond (usually with a few fractions of a carat), you can ask to add two small and inexpensive ones to the sides: it will greatly increase the brightness of the jewel.

2 If you have a brilliant cut diamond you might consider turning it upside down, leaving the pointed part on the outside, perhaps surrounded by a crown of other small diamonds. But be careful that the visible surface of the stone does not decrease too much.

3 If the diamond is set on yellow gold, you could change and choose to combine it with white gold, or vice versa: the ring will have a completely different appearance.

4 A diamond also goes well with classic colored gems such as emeralds, rubies and sapphires. Two little touches of color can make all the difference.

Consult a jeweler

Before making the decision to modify your ring, consider a few things. That ring is also linked to a memory: if it is a moment that you want to erase from your memory, proceed without worrying. But if not, think twice before proceeding. If, on the other hand, you have any idea how you would like a new ring, talk to a trusted jeweler. Ask how much the type of stone (diamond or other gem) you want to use costs. First show you a similar one, of the same weight and size: you will avoid being disappointed when you go to collect the ring. Don’t forget to ask for the cost in advance. Finally, before entrusting the ring to the jeweler, take a picture of the jewel, from both sides. Make sure to illuminate it well and carefully preserve the image. If, after the work of the jeweler, something does not convince you, you could return to the starting ring. And, in any case, it will remind you of what your engagement ring was originally like.

Sotheby’s presents a record-breaking blue diamond




It’s record time for diamonds. This time in the most precious competition in the world, Sotheby’s came first, presenting The De Beers Cullinan Blue, the name of an extraordinary natural diamond. The stone is also one of the most precious blue diamonds ever offered at auction: its value is estimated at over 48 million dollars. The blue diamond, with a rectangular stepped cut, weighs 15.10 carats and was recently cut from an exceptional rough stone discovered in April 2021. In addition, it is the largest internally flawless step cut vivid blue diamond that the Gemological Institute of America (Gia) has ever ranked.

Il diamante The De Beers Cullinan Blue
Il diamante The De Beers Cullinan Blue

Blue diamonds of this type, quality and weight are exceptionally rare. There are only five examples exceeding 10 carats that have been auctioned, but none have exceeded 15 carats. The De Beers Cullinan Blue is the most important piece of Sotheby’s Hong Kong Luxury Week: it will be offered in a single lot live auction in late April 2022 (exact date is yet to be determined). Given the global interest in a treasure of this nature, the diamond will first be presented on a world tour in New York, London, Dubai, Singapore, Shanghai, Beijing, Shenzhen and Taipei.

Blue diamonds of any kind are rare on the market, but this is the rarest of the rare; nothing of remotely similar calibre has appeared at auction in recent years. Hundreds of millions of years in the making, this extraordinary blue diamond is surely one of nature’s finest creations. Now brought to dazzling life by the hand of one of the world’s most skillful cutters, it is the ultimate masterpiece – as rare and desirable as the very greatest works of art. At a time of unprecedented demand for the finest, world-class, coloured diamonds, we are incredibly excited to bring to the market what is sure to become one of the most celebrated gems in the world.
Patti Wong, President of Sotheby’s Asia

The diamond was discovered in the Cullinan mine in South Africa in 2021, one of the very few sources of extremely rare blue diamonds in the world. Over the past year, De Beers has partnered with his partner, Diacore, one of the most experienced diamond master cutters, to cut and polish the stunning rough diamond and bring The De Beers Cullinan Blue to life.

The De Beers Cullinan Blue stands as a proud masterpiece that has been gifted from nature with the hues of the sky and sea, perfected through a step-cut that is bold, distinctive and masterful. Among the rarest of stones in what is arguably the most desirable of colours – powerful and vivid, but at the same time calm and majestic – it must surely rank among the greatest wonders of the natural world. It is literally irresistible.
Wenhao Yu, Chairman of Jewelery and Watches at Sotheby’s Asia

While other colored diamonds can be found in mines around the world, there are very few sources of blue diamonds, most of which are recovered from the Cullinan mine in South Africa. Cullinan has produced many of the most famous diamonds in the world, including the 530-carat Great Star of Africa, the largest faceted colorless diamond in the world. Cullinan continues to produce some of the most extraordinary treasures in the world, including all De Beers Millennium blue diamonds. Notably, the De Beers Millennium Jewel 4, a 10.10-carat oval-shaped Fancy Vivid blue sold for $ 31.8 million at Sotheby’s Hong Kong in April 2016.

All about diamonds and carats




Why are diamonds measured in carats (as well as for transparency, cut and purity)? And why are the carats of diamonds different from the carats that are used for gold? Questions that are often addressed to the gioiellis.com editorial staff. If you do not know what is meant by carat about diamonds or gold, here is a quick explanation.

History. It all starts with beans. That’s right: the word carat, or carat, comes from the Arabic word qīrāṭ, which means bean pod. But also the ancient Greeks called beans and carobs with the name of keration. But what does a diamond have in common with beans? Simple: in ancient times the seeds, which were the size of most gems, were used to determine the weight of diamonds. But a couple of centuries ago it was decided to establish a common value (not all beans are the same, after all). One carat, for diamonds, has been set at a weight of 200 milligrams or, if you prefer, 0.2 grams. Thus, a 1-carat diamond weighs 0.20 grams (equivalent to 0.007 ounces), a 2-carat diamond weighs 0.4 grams, and so on. You will more easily find jewelry made up of diamonds weighing much less than 1 carat. For example, a 0.05-carat diamond ring, which is a fairly common size, has a stone that weighs 0.01 grams (equivalent to 0.0004 ounces). And there are also those who, like Tiffany, measure diamonds up to one thousandth of a carat.

Shape and weight of diamonds. Carats are not everything: for the same weight, a diamond can appear more or less large according to the chosen cut, for example, brilliant (round), princess, oval, cushion, marquise, emerald, radiant or heart. In short, the carat weight does not indicate exactly the size. You may also read the abbreviation Tw: it is an abbreviation that is used for total weight, which is usually used to indicate the total weight of all the diamonds in a jewel.

The karat of gold. The word carat is also used for gold, but it indicates something completely different. For gold, the amount of karats measures the percentage of pure metal used: 24 karat gold means that 100% is pure gold. 18-karat gold indicates that 25% of the jewel is made up of other metals, such as silver, copper, palladium. A 14 karat gold ring is an alloy with 14 parts of gold and 10 parts of other metals. But why are there 24 karats of gold? The proportion dates back to the time of the ancient Romans at the time of the Emperor Constantine, who considered 24 silique, a silver coin, equal to a solid of gold, as the most valuable coin was called. For 1500 years, more or less, gold has therefore had two values: weight (in grams or ounces) and purity (carats).

Carat and Karat. In many languages ​​the word carat between diamond and gold is indistinguishable. In English, however, Carat is used for diamonds (and gems in general) and indicates the weight, while Karat is used for gold (abbreviated Kts). Thus it is much more precise and there is no confusion.

Diamonds, an Amour with 77 faces

/




A diamond with 77 facets: it’s called Crisscut and is mounted in the jewels of the L’Amour collection by Christopher Designs ♦

Love is true love only if it is excessive, right? It is something that involves, that drives us to do great things, to challenge rules and clichés. And, then, why a diamond donated for love should not be in tune with this pleasant madness? Christopher Slowinski must have thought in this way when he founded Christopher Designs, in 1981. Born in Poland, Slowinski has worked as a simple apprentice with master craftsmen even after moving to the United States, in New York. City.

Long story short: he invented Crisscut, a patented diamond cut that increases to 77 the little faces of the stones, instead of the traditional 48. This cut makes it even brighter and more brilliant diamond. The Crisscut was initially applied to the emerald cut, to increase their reflexes. But then Christopher has also extended the concept to other cuts such as the Asscher and cushion until you get to 109 facets in a round stone. But the brilliant Crisscut actually has straight walls 12 and 12 sides and this further increases the brightness. The diamonds have become the L’Amour collection. Which has no limits, of course.

Brighter jewels with the Floeting Diamond

/




Even an ancient and seemingly eternal technique can be innovated. The setting of a diamond on a ring seemed, until yesterday, something without too many possibilities to change. The most used technique is the one with the four or six prongs that hold the diamond still on the metal circular band: the classic solitaire. But from New Zealand comes a novelty: the Floeting Diamond. This is a new diamond setting system, which promises to increase the brightness of the stone and, at the same time, to make the jewel even safer, which would thus have less risk of making the stone come off. The inventor is called Ian Douglas and he is a jewelry master and former Auckland retailer.

With Floeting Diamond the stone is protected by a frame made with a special titanium alloy: a system that is over 20% stronger than traditional frames. Floeting diamonds come from one of the largest diamond cutting facilities in the world, certified by the Responsible Jewelery Council and using ethically sourced stones. The Floeting setting stops the diamond in the middle, between the top and the bottom, which ends in a point. Most of the gem, therefore, remains positioned above the setting. To keep the stone steady, laser-cut grooves are made in the diamond just below the girdle. The stone is then inserted into the frame.

This new way of stopping the diamond is mainly used to create solitaire rings, but also earrings or points of light. Since the stone is open on four sides, more light enters the diamond, increasing reflections. This type of setting can be used for oval, emerald, pear cut diamonds and also other precious stones. But don’t try to copy it: the system is patented.

Why are they called diamonds (and 21 more surprising news)

Diamonds, the most known and loved gemstone, hides many secrets: here are 22 of them you need to know ♦ ︎

You know that diamond is the hardest material that exists and it is forever. You also know what the 4 C’s are (and if you don’t know it read here). And you also know that diamonds can also be colored. But there are 22 other amazing aspects of the diamond that you need to know.

1 Do you know why diamonds are called that? The name derives from the ancient Greek word ἀδάμας (adámas), which means unalterable, indestructible, untamed.
2 How long has humanity been searching for and wearing diamonds? According to anthropologists, diamonds were recognized and extracted for the first time in India, between 600 and 300 years ago. Diamonds were found in alluvial deposits along the rivers Penner, Krishna and Godavari.
3 It is well known that the diamond has the maximum hardness. Less known that it also has a high thermal conductivity, that is the aptitude to transmit heat. This is also why diamonds are used in many industrial applications such as cutting and polishing tools.

4 If you can, bring your ear close to a diamond and listen. Well, you need a diamond of a certain size, but know that through this gem the sound passes at the highest speed.
5 Even if diamonds are heat transmission, the gems also has a high electrical resistance. You don’t get thunderstruck through a diamond.
6 Diamonds are hard, but can scratch other diamonds. And this can cause damage to one or both stones. When storing them, make sure that the stones do not collide.

7 Another interesting property of diamond: it is chemically inert, ie it does not react with most corrosive substances and also has excellent biological compatibility. No diamond allergy is known (thankfully).
8 Colored diamonds are determined by small defects or impurities inside them. In particular, when the diamond is blue it means that inside it has boron, yellow or brown nitrogen atoms, if it is green it is because it has been exposed to radiation, such as violet, pink, orange or red.
9 Nitrogen, responsible for the yellow and brown color, is by far the most common impurity found in diamonds.

10 The diamond also has a high optical dispersion (ability to disperse light of different colors) and for this reason it is so bright.
11 How old are diamonds? Much: most natural diamonds are between 1 billion and 3.5 billion years old.
12 Where do diamonds come from? From the belly of the Earth. Most were formed at depths of between 150 and 250 kilometers in the earth’s mantle and some as deep as 800 kilometers. But today they are found at lower depths, because they have been brought to the surface by volcanic eruptions and deposited in rocks known as kimberlite and lamproiti.

13 You will have heard that diamonds are, in practice, compressed coal. But it’s false. Coal is a material formed from prehistoric buried plants, while most diamonds are much older than the first terrestrial plants. However, it is possible that diamonds can be formed from coal in some particular areas, but the diamonds thus formed are very rare.
14 Would you like to have so many diamonds? Then go into space. Although diamonds on Earth are rare, they are very common in meteorites: about 3% of the carbon found is in the form of nanodiamonds, only a few nanometers (one millionth of a millimeter) large. But, according to astronomers, some extrasolar planets could be almost entirely composed of diamonds.
15 The diamond trade is very concentrated: around 90% of the world’s diamonds are cut and polished in Surat, India.

16 The most precious stones are cut in Antwerp’s cutting and trading centers in Belgium, where the International Gemological Institute is based, in London, in the diamond district in New York, at the Diamond Exchange District of Tel Aviv and Amsterdam.
17 When cutting a rough diamond the weight reduction can be in the order of 50%.
18 Cut a diamond is not easy: the stone can be divided by a single well calculated shot, with a hammer and a pointed instrument. But it is a very risky system. In practice, a precision diamond saw is usually used, which is a more reliable but long system.

19 Colored diamonds are in fashion. But only a few years ago: those browns were a large part of diamond production, but they were used mainly for industrial purposes.
20 Brown diamonds were once not valued on the diamond color scale. But after the development of the Argyle diamond mine in Australia, in 1986, they were considered acceptable gems and used in jewelry.

21 The Argyle mine in Australia, with its 35,000,000 carats (7,000 kg) of diamonds per year, produces about a third of global production of natural diamonds. And 80% of Argyle diamonds are brown.
22 What was the biggest diamond theft? It took place in February 2013 at Brussels airport. The thieves fled with gems worth an estimated 50 million dollars. But later the gang was arrested and some of the diamonds were recovered.

Le Soleil d’Or, super diamond signed by Fred




In the French group LVMH, the largest cluster of luxury brands, from Tiffany to Dior, from Bulgari to Chaumet (but the complete list would be very long) there is also Fred, a Maison with roots that go back to the 1930s. Although most of Fred’s jewelry can be qualified as fine jewelry, of moderate luxury, often with a sporty design like the best-known collection, Force 10, the brand is ready to unleash an exceptional hit: a large yellow diamond, called Soleil d’Or. The stone, which marked the history of the Maison, is now returning to Fred’s heritage, 44 years after its first presentation to the public.

It is a maxi stone: it weighs 101.57 carats and has a color classified as fancy intense yellow, which places it among the gems of great value. The Soleil d’Or diamond was named in 1977 by the founder, Henri Samuel. The gem will be visible to the public in the fall of 2022, in Paris, in a retrospective exhibition on the brand. Before its official presentation, almost half a century ago, the stone was the focus of a lunch attended by the press and some friends of the Maison, such as actress Margaux Hemingway, who was portrayed with the diamond. Cheerful note: Margaux Hemingway, while she handled the stone, pretended to lose it. After a few moments of chaos, the actress made her reappear between her teeth.

John Apel’s American Dream

//




Before judging John Apel jewels, you need to know the true passions of the founder of the American brand, John Apelian: oil painting and gardening. It is not a very common aspect among jewelry designers. But John Apelian has a different story from the others: he was born in Istanbul, Turkey, learning the family business: leather tanning. And his unique combination of chemical expertise and innate creative talent allowed him to introduce new colors into the leather tanning process. Then, he taught in a technical school, but he also worked with a small jewelry company. There, the spark for jewelry struck.

In 1976, John and his wife Hilda emigrated to the United States, where the designer opened a small jewelry repair shop and, in 1991, founded his own manufacturing and design company under the Italian name DiLaro. Fortunately, in 2006, Apelian chose to change the name of the brand with one closer to him. For his jewels he uses platinum or 18 karat gold, together with gems, while for his creations he is inspired by nature. Among the features there is also a line with rose-cut diamonds, a traditional shape widely used in the East, because the origins, after all, are never forgotten.
