www.sothebys.com The Farnese Blue, a historic 6.16-carat pear-shaped fancy dark grey-blue diamond to be auctioned at Sotheby s Geneva sale of Magnificent Jewels and Noble Jewels on May 15th / Estimate: CHF 3,500,000 5,000,000 Excitement is at a high pitch each May with the two leading auction houses Sotheby s and Christie s each hosting a sale of remarkable signed high jewels, one day apart in Geneva. On these two exceptional occasions, it is possible to see and bid for pieces of high jewellery and extremely rare gemstones that have not been seen publicly before. There was a case in point this year with Sotheby s once again unearthing rare gems. At this level, rare hardly begins to describe it. The Farnese Blue 6.16-carat diamond was given to Elisabeth Farnese, Queen of Spain in 1715; and was subsequently passed down through four of Europe s most important royal families. With such a lineage, such a mesmerizing dark grey-blue hue, and such a high carat weight, there is a chance this is the only time one will ever be able to see this stone, especially when you know that it is now emerging onto the market for the first time in three centuries.

These are two of the largest, purest white diamonds ever to come to auction, the team says. Both weighing over 50 carats and matching perfectly all critical criteria, together estimated in excess of US$15 million, each diamond ranks as the second largest of its kind ever to appear on the auction market. Sotheby s with its Sotheby s Diamonds arm (whose creations Exceptional diamond ring set with one round brilliant-cut Type IIa diamond weighing 51.71 carats and D colour, flawless, excellent cut, polish and symmetry / Estimate: CHF 7,870,000-9,100,000 are often featured in my articles) is certainly one the biggest players when it comes to exceptional flawless gems. Evidence of this in the recent sale to a private collector of the 102.34-carat most rare, purest white diamond known to man (see Notes on an Obsession article from March 2018), and at a price per carat that far exceeds that for any colourless diamond sold at auction, augurs well for Sotheby s Magnificent Jewels and Noble Jewels on May 15th.

www.alvr.com Fabergé Dessert Set by workmaster Julius Rappoport, c.1890, in silver, copper, and gold. This set of fruit and cheese cutlery illustrates Fabergé s fondness for Japonisme. Handles have been repurposed from a traditional Japanese utility knife called a kogatana. Most are signed by master craftsmen, such as Ishiguro Masaharu, Nakajima Toshiharu and Hamano Masayuki. Each handle is uniquely ornamented with Japanese motifs. Metalwork techniques include shibuichi, an alloy of silver and copper blended in varied proportions to achieve colors ranging from grey to blue or green. Others are made of copper, and some are shakudo, an alloy of gold and copper treated to resemble lacquer. Included in the exhibition are superb works such as a gift to ballerina Anna Pavlova presented by Czar Nicholas II and his wife Alexandra Feodorovna; a sculpture related to Charles Darwin; a five-color gold double marriage cup; a Japanese-inspired dessert cutlery set; a potato carved from pink-brown agate; and Vara Panina (the gypsy singer), the most famous of the Fabergé figurines, along with many other masterpieces.
