Archduke Joseph diamond fetches $26m at auction
GENEVA (REUTERS) - A huge, internally flawless diamond from India’s fabled Golconda mines was sold at auction in Geneva on Tuesday night for a record 20.355 million Swiss francs (S$26.27 million), Christie’s said.
The rare, colourless stone weighing 76.02 carats, and roughly the size of a large strawberry, once belonged to Archduke Joseph August of Austria (1872-1962), a prince of the Hungarian line of the Habsburgs.
Its pre-sale estimate was 15-to-25 million Swiss francs and it fetched more than double the price paid for it at auction almost two decades ago.
“It is a world record for a Golconda diamond and a world record price per carat for a colourless diamond,” Francois Curiel, director of the international jewellery department at Christie’s, told reporters.
