A new world record for any heart-shaped diamond ever sold at auction was set this week when Christies secured £12.5m for a stone set into a striking necklace by Parisian jeweller Boehmer et Bassenge.

The D colour, 92.15ct, heart-shaped diamond, set by Boehmer et Bassenge, was put up for auction at the Magnificent Jewels auctions at Christie’s Geneva.

After three minutes of bidding in the room and telephone, the sale set a new record for any heart-shaped diamond sold at auction when it went for $14.9 (£12.5m).


This was the top lot of the auction house’s luxury sales, and surpasses the previous record for a heart-shaped diamond – which was set by Christie’s in May 2011 when the auction house sold a stone for $10.9 million (£8.3m).

Strong overall sell through rates of 88% by lot, for the first set of Luxury sales this season confirms that this market is growing with significant additional participation from Asia. New clients have been transacting with Christie’s all week, with more than 100 new registrants for the Important Watches sale alone.

“A fantastic result was achieved for the heart-shaped diamond which sold for just under $15 million, setting a new record for a heart-shaped diamond sold at auction, surpassing the previous record of $10.9 million set at Christie’s in May 2011,” remarks François Curiel, the chairman for Christie’s for Europe and Asia.

He concludes: “The Luxury Sales this week were well attended both in the saleroom itself as well as a significant increase in online bidding this season across all three sales. Geneva has proven once again to be the right place to offer the most exquisite jewels, the rarest wines and important watches.
