76-Carat Archduke Joseph Diamond Fetches $21.5 Million

LAST UPDATE ON: March 24th, 2023

On November 13, the legendary Archduke Joseph Diamond sold for a record $21.5 million at Christie’s Geneva Magnificent Jewels action. The 76-carat diamond was the property of the Archduke Joseph August of Austria, Palatine of Hungary (1872-1962). The D-color and internally-flawless clarity diamond was named after the Archduke, who was the great-grandson of Emperor Leopold II and King Louis Philippe of France through his father and mother respectively.

The incredible diamond is said to be from the famed Indian Golconda mines, an ancient source which once yielded some of the world’s most renowned diamonds, including the Koh-i-noor, the Regent, and the Hope.

“In the busiest saleroom witnessed at the Four Seasons hotel des Bergues in Geneva in recent years, the Archduke Joseph Diamond of 76.02 carats sold for $21.5, a world record price per carat for a colourless diamond. The historical gem led Christie’s jewellery auction which totalled $85 million dollars,” said François Curiel, president of Christie’s Switzerland.
