Golconda Diamonds and Royal Connections
The Archduke Joseph Diamond apart, many famed diamonds that have a royal lineage and are part of crown jewels of various countries including Iran, are believed to have been extracted from the fabled Golconda mines in India. Among these are the Koh-i-Noor, presently on display at the Tower of London and set in the crown made for the late Queen Elizabeth, The Queen Mother, for the 1937 coronation. According to the official Web site of the British Monarchy, the Koh-i-Noor diamond, which has a controversial history with regard to its first owner, was gifted to Queen Victoria in 1850 during the British Raj. At 105.6 carat, it is one of the largest known diamonds.
The Archduke Joseph Diamond's former owner, Alfredo J. Molina, who is also the CEO of America's Black, Starr & Frost jewelers, believes it is yet another Golconda diamond "fit" for a queen.
"I am thrilled but not surprised that the Archduke Joseph Diamond should have fetched such a high price. It is considered the finest and largest perfect Golconda diamond ever to appear at auction, with a noble lineage and royal provenance which literally 'Fit for a Queen'," he said.
