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
