With the auction season starting off with a bang, Christie’s and Sotheby’s are actually saving the best for last. More specifically, the largest perfect Golconda diamond, known familiarly as the Archduke Joseph Diamond after its one-time owner, is the star lot of Christie’s Geneva Magnificent Jewels auction to take place on November 13th, 2012. A whopping 76.02 carats and internally flawless, this majestic gem is estimated at $15 million but is expected to fetch well over that amount. According to Bloomberg, the upper valuation of $328,861 per carat is a record for a colorless diamond. This isn’t the first time the Archduke has created a stir at Christie’s Geneva: the auction house offered the stone for sale in November 1993, where it sold for 9.7 million Swiss francs – the equivalent of $10.5 million today. Other famous diamonds originating from the legendary Golconda mines in India include the Dresden Green, the blue Hope, and the Koh-i-Noor. Named after Archduke Joseph August Viktor Klemens Maria, son of Archduke Joseph Carl of Austria and Princess Clothilde of Saxe-Coburg and Gotha, and a member of the royal House of Habsburg, the diamond had been in the family’s possession until the 1930s. Christie’s has not revealed who the current owner is, however. This stone should cause quite a stir next month!
