Rare Burmese ruby sells for €26.6m
A rare Burmese ruby set in a platinum ring with diamonds has sold for $30.3m (€26.6m), setting a world auction record for any ruby and for any stone by Cartier, according to Sotheby's.
The buyer and history of the piece, with the ruby weighing in at 25.59 carats, was not disclosed. It was auctioned as part of the annual Magnificent and Noble Jewels sale by Sotheby's in Geneva.
The price of the cushion-shaped "Sunrise Ruby" had been estimated prior to the sale at $12m to $18m.
It is known for its "pigeon blood" red colour and is set between heptagon-shaped diamonds weighing 2.47 and 2.70 carats. The piece is signed Cartier.
The auction house called a natural ruby from Burma of this size and colour extremely rare. The ring also broke an auction record for any ruby per carat.
In all, the sale totalled $160.9m and included three other centrepieces from Cartier.
