Rivière jewelery guide

Published on December 26, 2023

Rivière and Triple X: Two terms that are sometimes used in jewelery. You want to know what Rivière and Triple X mean? Read here ♦

Some time ago, in New York, in a Bonhams auction, a 51 diamond rivière necklace, rated triple X-cut, was sold for $ 1.2 million. It was been the jewel that has reached the highest price. Each diamond of the necklace was accompanied by a certificate from the Gemological Institute of America. The diamonds in question weigh over 70 carats: in the necklace are joined by a 2.04-carat heart-shaped clip. The stones are mounted in platinum. But do you know what the rivière and triple X definitions mean?

Rivière. The term rivière derives from the French word that means river. In jewelry, it indicates a row of stones that are the same size or scale, that is, from larger to gradually smaller. It is also a way to make the most of the stones of different sizes and order them in a geometric pattern. It is a set often used for diamond necklaces, more rarely with other stones. Very fashionable in England during the Georgian period, rivière style necklaces are still popular today.

Rivière necklaces are usually designed without ornaments, to enhance the stones used. But in some cases these necklaces hide a small ring that allow you to add a pendant. There is also a practical reason when it comes to necklaces with stones of different sizes: enhancing the larger ones, placing them on the front of the necklace, makes the jewel more slender. The perspective effect of the stones that become smaller when they approach the nape of the neck also makes the necklace more slender. Finally, it is difficult for a jeweler to have so many stones of the same size and quality. This solves the problem.

Triple X. Also known as Triple Ex, it is an informal denomination, mostly in the commerce sector, which means a diamond that has excellent chiselling, symmetry and cutting. The definition is only intended for brilliant cutting diamonds.

Tripla X. Conosciuta anche come «Triple Ex», è una denominazione informale, per lo più nel settore del commercio, che significa un diamante che ha ottima cesellatura, simmetria e taglio. La definizione è destinata solo ai diamanti taglio brillante.

How much does investing in vintage jewelry make?

According to the British auction house Bonhams, there is a treasure in your drawers: vintage jewelery has appreciated more than any other good ♦
Investing in jewels, provided you keep them for a long time, can be a bargain. The British auction house Bonhams claims it. According to an analysis conducted some time ago by the auction company, vintage jewelry has gained more than 80 percent in value over the past ten years. Yet, most of the owners of these jewels don’t fully realize it. Jewelery from the Art Deco period (1920s and 1930s), as well as pieces dating back to the Belle Epoque (1890-1915), have increased in value by 88 percent over the past decade. And post-war jewelry has gone up 70 percent in value. The auction house also makes the comparison with another capital asset: your own home.

In Great Britain, for example, average house prices have increased by 47 per cent over the same period considered. And in other countries, such as Italy, in the same period there was even a drop in property prices, even if they are now recovering. Attention: the increase in value of vintage jewels works for quality jewels, certainly not for jewels of unknown brands or uncertain workmanship. Maisons like Cartier or Van Cleef & Arpels, for example, according to Bonhams are a guarantee of value that is preserved over time, even if sometimes the jewels are without labels. Therefore, it is advisable to carefully preserve the inherited jewels, even if they seem out of date. They could be of substantial value, although not all period jewelry is truly valuable.

Jean Ghika, head of the jewelery sector for the United States and Europe of Bonhams, also gave an example: that of an elderly lady who thought she had a useless piece of jewelery in her drawer, but which turned out to be a rare Chanel necklace designed by Coco Chanel herself. The necklace was appraised by Bonhams (who spotted a small engraved Chanel name) and sold for $83,188, based on a pre-sale estimate of $4,858-7,287. You better start looking in your drawers right away: maybe there is a treasure.

If you want to buy a vintage jewel as an investment, however, you must not choose at random. A vintage or period jewel is not necessarily something that is revalued over time. It is necessary to carefully evaluate the quality of the jewel, if it is worn, if it has damaged or worn elements, if it has precious gems. Another factor that greatly influences is the origin, which must be certified. Finally, it must be taken into account that a vintage jewel is more likely to increase its value if it was made by a large Maison, or if it was designed by famous jewelers or designers.

Much of the purchase of vintage jewelry is done through auctions. Often jewels of great value come up for auction and it is not uncommon for interesting prices to be found. But that’s not always the case. First of all, it is likely that those who trade in jewelry and are experts in the vintage market have already set their sights on the most interesting pieces and are willing to spend more. You also have to consider that the prices established during an auction must be supplemented by the mark-up for the auction house that organized the sale. Taxes must be added, if provided for by local laws, and above all the auction fees which vary but can even reach 25% of the clearing price. An aspect to take into account before buying a vintage jewel at auction.

“We were honored to have been chosen to offer this magnificent pink diamond to our customers and we were delighted to see how much the sale has done,” commented Emily Barber, director of Bonhams UK jewelry. “This is due to a number of factors: its size – it is extremely rare to see a rose over five carats on the market today; its uniform color saturation and its extraordinarily elegant cut. Large pink diamonds continue to increase in value year after year. They are highly desirable for demanding collectors, given their rarity and limited supply. A diamond like this would surely be one of the most precious pieces in an important collection of jewels “.

From the Olympic gold to the gold of the jewels: Bonhams auctioned those of the former champion Katherine Domyan ♦ ︎

Gold attracts gold. It is not a magnetic effect (in fact, gold does not behave like iron), but a general principle. Katherine Domyan, twice a gold medalist in the Olympic games for Hungary, has become fond of another kind of gold in her life, that of jewels. And now Bonhams, in New York, at 21 september auctioned the collection of the former athlete, who disappeared in October 2017.

Engagement rings: here are the five most expensive ever celebrity gifts like Paris Hilton, Beyoncé or Grace Kelly. The one with the highest price is … ♦

What have been the five top engagement rings so far? There is no official ranking. There are even cases like that of Paris Hilton, who lost the $ 2 million engagement ring (the latest in a series) that was given to her by her fiancé and promised husband, Chris Zylka. In any case, it is possible to identify the engagement rings that have been awarded and have set a hammer price at a public auction. In short, on many rings given to actresses or famous women you can make assumptions. On these, instead, there is a certainty. So, here are the most expensive engagement rings.

What are the five top engagement rings of the world? You can establish a ranking considering the hammer price at auction or at shop. In this case, here are the winners.

L'anello Trombino con diamante Blu di Bulgari — The Trombino ring with blue diamond by Bulgari

The ring more expensive is signed Bulgari. On 24 April 2013, the «Trombino ring» was sold in London by auction house Bonhams to 7.9 million euro, equivalent to 9.5 million dollars. It is a ring with a 15.30 carats blue diamond. The diamond is cut to cushion within a pavé brilliant-cut diamonds and baguette cut diamonds. Blue diamonds are extremely rare. Over the last ten years, only thirty blue diamonds over five carats were beaten at auction in the world. Few if we compare with the tens of thousands of colorless diamonds sold in the same period. The blue color of the diamond is caused by trace of boron, that makes diamonds semi-conductors of electricity: the blue color is intensified when the diamond is hot. Not only: these diamonds can also become phosphorescent exposed to short wave UV light and project a red glow for a few seconds. The diamond is mounted in a ring Trombino created by Bulgari in the mid-1960s. The ring was bought by Laurence Graff, of Graff Diamonds.

Elizabeth Taylor con l'anello di fidanzamento — Elizabeth Taylor with engagement ring

Diamond ring by 33.19 carat Krupp and Taylor-Burton, sold for $ 8.8 million. The ring was given to Elizabeth Taylor by Richard Burton. The diamonds, Asscher-cut, has long been worn by Elizabeth Taylor, before being sold at auction by Christie’s in 2011 for a price of $ 8.8 million. Originally the ring was owned by the German actress Vera Krupp, wife of industrialist Alfred Krupp.

Beyoncé con l'anello da 5 milioni di dollari — Beyoncé with the $5 million ring

In third place is the Beyoncé’s 18-carat diamond ring valued at $ 5,000,000, a gift from rapper Jay Z. The ring is signed Lorraine Schwartz and features a diamond-cut emerald. The diamond, colorless, is recognized to be one of the best in the world.

Paris Hilton con l'anello porta jella — Paris Hilton with bad luck ring

In fourth place is the ring of Paris Hilton, with a 24-carat diamond worth $ 4.7 million. The heiress-starlet has received the ring from the young greek namesake Paris Latsis. Their happiness was ended rapidly, but the 24-carat diamond with an emerald-cut mounted on a white gold band retains its charm. Paris Hilton, however, do not have it anymore: after breaking the engagement, the ring was sold at auction to raise funds for the victims of Hurricane Katrina. But for nearly half of its original price.

Grace Kelly con l'anello di diamanti taglio smeraldo — Grace Kelly with the emerald cut diamond ring

In fifth place the Grace Kelly’s Cartier ring , a 10:47 carat diamond, worth 4.06 million dollars, fruit of love of Prince Rainier III of Monaco. This also has an emerald cut diamond, and is known to be one of the best among those produced by Cartier. But if inflation is taken into account, the cost today would exceed 44 million.

Rubies, sapphires, diamonds and 16 pieces by David Webb at Bonhams auction in New York ♦ ︎
Even if you do not have the money to buy the magnificent jewels of the magnificent auctions held in the wealth capitals, first of all Geneva, London, Hong Kong and New York, browsing the catalogs can be enjoyable. You can find exceptional jewels discovered, true masterpieces not only for their estimated value, but also for their artistic quality.
Also the auction scheduled by Bonhams in New York for April 17, 2018 (133 lots) does not miss interesting pieces in the catalog. A solitaire ring with premium quality, brilliant cut, 10,01 carats is the most valuable piece, with an estimated 500,000-700,000 dollars. But, if you are not a diamond enthusiast or an investor who wants to close the ring in a safe, it is not the most pleasant piece to watch. Better, for example, the Art Déco bracelet with rubies and diamonds by Cartier, dated around 1935. It has contrasting rubies with white diamonds, in seven rows, interspersed with baguette-cut diamond bars, with other old-cut diamonds. Rubies are of Burmese origin and not heated. With rubies (50) is also composed of a necklace of Bulgari, with oval-shaped graduated stones, the largest weighing about 2.15 carats, alternating with round brilliant-cut round diamonds. Rubies are of Burmese origin (Myanmar). In the catalog there is also a ring of rubies and diamonds by Mermod & Jaccard.
Rubies are the fashion stone at the moment, but sapphires never set. At the auction of Bonhams, for example, a ring with 9.85 carats of Kashmir sapphire and diamonds is estimated at 80.000-120.000 dollars, while a pendant necklace with Sri Lanka sapphire of 40.07 carats and diamonds rises to 280.000- 320.000 .
The David Webb jewelery
One of the reasons of interest of the auction are also the 16 pieces by David Webb. The American designer was famous for his large and daring jewels, in which he also used materials such as exotic shells, carved rock crystal, enamel and coral. The collection that Bonhams will offer includes a bracelet with fox-head diamonds, diamonds, emeralds, rubies and enamels: a perfect example of Webb’s love for jewelry in the shape of animals, made with enamels, diamonds, emeralds and rubies.

Jewels and stones that will have more value in 2018

The auction house Bonhams has analyzed the trend of jewelry and stones most in demand and that will increase in value. For example, rubies and … ♦ ︎
What treasure have you hidden at home? Or in a bank safe? Perhaps you do not know that, but like for paintings or stock shares, even jewels are subject to variation in their value. Stones that twenty years ago were scarcely considered or even referred to as defective, such as brown diamonds, are now also used for high jewelery. In short, it is good to know the value of what you have.
The Bonhams auction house, for example, has revealed to the Professional Jeweler website what jewels are supposed to be more in demand in 2018 and, therefore, get a higher price. Here are the ten precious that in 2018 will increase in value according to Jean Ghika, Bonhams world jewelry director.
1) Colored diamonds. If ten years ago a vivid blue diamond was estimated at 200,000 to 300,000 dollars per carat, today the value has risen 2-3 million. A growth rate higher than the stock exchange or real estate. In short, it was an excellent investment. But now? According to Jean Ghika, “the market today is more informed and the beauty and rarity of these stones is fully appreciated. Colored diamonds of yellow, pink and blue in all sizes and hue are increasingly requested by buyers all over the world». And the value is set to rise, according to the Fancy Color Research Foundation. The average price of all blue diamonds rose by 8.1% over two years.
2) Rubies. Red stone is one of the most sought after in the last two years, surpassing the appeal of sapphires and emeralds. Bonhams, for example, brings an art deco ring from Lacloche, with a five-carat non-heated Burmese ruby, sold for £ 30,000 in 2007. An equivalent ruby on a Cartier ring has been sold at over £ 362,000 recently , with an increase of 1,108% in just seven years.
3) White diamonds. They remain among the right choices to preserve the value of a jewel. According to the auction house, there is a growing interest in diamonds with an antique, handmade cut from the Victorian, Edwardian and Art Deco period. They have a great charm and are distinguished compared to perfectly cut diamonds of nowadays.
4) Sapphires. Although slightly less than the ruby, the sapphire maintains a great appeal. Also because, next to the classic blue color, sapphires are available in a wide variety of shades, even rare ones like the padparadscha (pinkish-orange). The rarity of some nuances makes the sapphire much sought after by collectors and, therefore, preserves or increases its value. Also because sapphires of historical mines, like those of Kashmir, are among the rarest and most sought after.
5) Emeralds. The same discourse of the sapphires also applies to the green stones par excellence. However, the value depends largely on the color of the stone and on the clarity. High quality untreated (certified) stones from Colombia are in high demand and have seen a significant increase in value over the past decade.
6) Belle Epoque and Art Déco. Late nineteenth and early twentieth century are two golden periods for jewelry and are increasingly appreciated. In the last decade the value of antique jewelry has increased by 54%. In particular, jewels of the period 1945-1975 increased by 88.9% and those of art deco (1920s and 1930s) and Belle Epoque (1890-1915) by 71.8%.
7) Jewels of great Maisons. Over time, the value of the jewels of major brands resist better. But, even better, in recent years have seen prices rally. Cartier, Van Cleef & Arpels, Bulgari, Verdura, Suzanne Belperron and Tiffany, for example, are increasingly requested brands at auction.
8) Natural pearls. Pearls yes, but not cultivated. They are those who have seen their value multiply in recent years. The data of Art Market Research, reports Professional Jeweler, indicate a 286.1% increase in the price of natural pearls in the last decade.
9) Great designers. There is not only the signature of the great Maison to raise the price of jewels. Even the jewels of artists or designers such as Suzanne Belperron, Coco Chanel, Hemmerle, Georges Braque, Daniel Brush or Andrew Grima are in great demand.
10) Spinels. Red is fashionable, but it is not said to be ruby. The spinels are very similar to the rubies and are just as beautiful to see on a jewel. That’s why rings, necklaces or bracelets with large spinels are sprouting higher and higher prices. According to Bonhams, there is considerable interest in spinels and many collectors want to buy them. Federico Graglia

The Zsa Zsa Gabor diamond necklace at Bonhams auction in New York ♦ ︎
Zsa Zsa Gabor, who disappeared in 2016, was one of the most famous dives of the last century. Her career, started when she was elected with Miss Hungary in 1936, continued as a film actress. In over 50 years of career she has worked in more than 60 films, with directors such as Orson Welles, John Huston and Vincente Minnelli. In addition to leaving indelible memories to an entire generation (as well as its nine husbands), she has also left valuable jewels, one of her passions. For example, an “over-the-top gorgeous” diamond necklace will be auctioned on December 4 in New York by Bonhams. It is a rivière diamond necklace, with 45 brilliant rounds for a total of 66 carats. The necklace is the work of Harry Winston, who created it in 1964. The rivière necklaces are characterized by stones of different size (see also: What are rivièere and tripla X). In this case, the five central diamonds weigh 8.07, 6.34, 6.33, 5.35 and 4.88 carats. Their quality varies from F to I color and are VVS2 clarity. The value of the necklace is estimated at between 1.2 and 1.5 million dollars. But some enthusiast for the great actress’s could raise the price.
Zsa Zsa Gabor was a fan of jewels. She has been given a phrase that has become famous: “I never hated a man enough to give him his diamonds.” Federico Graglia

In September in auction by Bonhams in London 55 jewels designed by Andrew Grima ♦ ︎
Everything is ready for the new season of autumn auctions. On September 20th in London, the largest private collection of jewels dedicated to the Andrew Grima brand has been launched. To sell jewels comes the Bonhams auction house.
The charismatic Anglo-Italian jeweler Andrew Grima has been considered one of the most audacious and imaginative designers of the last century. He has been the reference jeweler for real, celebrity, socialite and artist during the legendary sixties and seventies. Her Majesty The Queen, Princess Margaret, Jackie Kennedy Onassis and the bond girl Ursula Andress were among her clients. Among his jewelery collectors today are designers such as Marc Jacobs and Miuccia Prada.
Grima was inspired by art, sculpture and the natural world, injecting a desperate need for originality and glamor in a stagnant, jewelery atmosphere of Great Britain at the time. He has created bold and unusual jewels whose laity value in their aesthetic composition and not just in the weight of carats of the stones used.
The collection, which will be sold by Bonhams, includes 55 jewels designed by Andrew Grima with some of the first pieces made in London in the 1960s and a selection from its most splendid period in the Seventies plus some special jewels in the Nineties and the latest products before death, in 2007.
There are also the clocks of the About Time collection for Omega, one of the most innovative, as well as works of the Rock Revival collection, with unusual cuts of precious stones.
After Andrew’s death, Maison’s work continues with the widow, Jojo, and her daughter Francesca. A number of lots for sale were exhibited at Grima’s retrospective exhibition held in London in 1991. Federico Graglia

The ring was composed of Tiffany using stones with a late nineteenth century cut. An old style that has its charm. Other prominent piece is a necklace with 17 diamonds, fancy yellow, to 47.34 carats (estimate between 350,000 and 550,000 dollars). Of note among the many proposed jewelry, a Cartier brooch of 1935, with a ruby marquise cut, pretty rare for this stone, with diamonds and baguette-cut, plus six cabochon rubies cut sugar loaf and diamonds. Estimate: 300-400,000 dollars. Federico Graglia

Anello solitaire con diamante taglio a pera

The Jackie Collins jewelry auction by Bonhams: there is also a Cartier necklace and a ring with a diamond pear cut.
If you’re one of the 500 million fans of Jackie Collins, you must know that Bonhams is organizing an auction in which sells the jewels of the writer who died in 2015. The auction is scheduled on 16 and 17 May 2017 in Los Angeles. For sale there are not only the jewelry that belonged to the best sellers writer, but also objects and works of art, books and her Jaguar.

Everything seems to come from one of the episodes of Dallas or Beautiful series. Suffice it to say that the house of Jackie Collins is set around a large swimming pool inspired by the iconic painting by David Hockney, A Bigger Splash. And, not surprisingly, the writer was the sister of one of the stars of Dallas, Joan Collins.

The jewelry, however, may also like to those who do not watch television soap operas. For example, a large necklace of diamonds and emeralds, with matching earrings. Or a necklace of Cartier Panthere series. Or, finally, a big diamond ring pear cut. Jacqueline Jill, better known as Jackie Collins (London, 4 October 1937 – Beverly Hills, 19 settember 2015) was a British novelist and actress naturalized US. She was the younger sister of actress Joan Collins, wrote 32 novels, including the best-seller list compiled by the New York Times: it is estimated that in his career as an author his titles have sold about 500 million copies.

It’s called Hope (Hope in English) and there are those who hope to get hold. The large gem is octagonal cutting, weighing 50.13 carats, set into jaws with round-cut diamonds. It is mounted in silver and gold, and it can be a brooch, a pendant, part of a larger jewel. Surely, however, this gem put on auction by Bonhams (September 24) it has a long history behind it. It is named after Henry Philip Hope (1774-1839), scion of a wealthy family of Anglo-Dutch merchants and bankers. Mr. Hope was a collector with a passion for precious gems. So he began to form his collection around 1800 and continued to collect precious stones until his death in 1839. His collection has grown to 700 gems and pearls, cataloged by the German jeweler Bram Hertz. The collection was dispersed after the death of mr. Hope. But some pieces, such as the spinel surrounded by diamonds (valued 230-310mila dollars) have emerged from the mists.
In any case, it is worth to tell something more. The Hope collection has been stored for years in a cabinet mahogany to 16 trays. The larger stones were placed in the drawers 14 and 16. The top drawer contained various types of pearls. The big baroque pearl eastern, known as The Hope Pearl, was the largest known natural pearl: 5 centimeters long and 11.5 centimeters in circumference, weighs 85 grams. The second and third drawer held colored diamonds included reddish orange, pink, bright blue-green hues, and a lot of yellow and brown. There were also 49 faceted diamonds from the legendary mines of Golconda (India), including a diamond briolette-cut 14.25 carat which was part of the crown jewels of Portugal. The most famous is the Hope diamond, the 45.52 carat intense blue that was in the drawer 16 and is now kept at the Smithsonian Museum in Washington. But not only: Hope had in the drawers a sapphire of 130 carats, 133 carats from an emerald which once adorned the turban Tipu Sultan (sultan of India), and one perfect 50 carat spinel.
