Historic diamond expected to set the benchmark for autumn auctions.

A 76.02 carat diamond will go under the hammer in November when Christie’s auctions the legendary Archduke Joseph Diamond at a sale in Geneva.

The stone, which can trace its origins back to ancient Golconda mines in India, is internally flawless and perfect colour.


It is expected to sell for over $15 million at the November 13 auction.

The sale is the star of Christie’s autumn jewellery buying season, and will establish a marker for the demand for top end diamonds and other stones in the current economic climate.

François Curiel, international head of Christie’s Jewellery Department, noted: “The magic of auction sometimes brings back great gems to our salerooms more than once. The Archduke Joseph Diamond created a sensation when Christie’s Geneva offered it for sale the first time in November 1993 where it realised CHF 9.7 million (US$ 6.5 million) – the equivalent of $10.5 million today. This November we have the privilege to give both new and established collectors the opportunity to own a piece of history once again.”
