A record-breaking diamond, Bulgari Laguna Blu sold for 25 million

This is the amount paid by an anonymous buyer over the phone at the Sotheby’s auction in Geneva

A blue diamond worth more than 25 million dollars that sets a new world record: this is the amount paid by an anonymous telephone buyer for the legendary Bulgari Laguna Blu, auctioned by Sotheby’s in Geneva, where the precious stone reappeared after half century. Sotheby’s has brought the clock back to pre-pandemic times by achieving the best performance with the sale of the Magnificent Jewels and Noble Jewels catalog of the last five years, since May 2018, realizing a total proceeds of 76,732,260 Swiss francs (85,431,762 dollars).

The top lot was the Bulgari Laguna Blu, which sold above its asking price to reach 22,625,100 Swiss francs (25,189,429 dollars; 23.2 million euros).

The Bulgari Laguna Blu is an extremely rare gemstone boasting exceptional color saturation and a vibrant oceanic blue, sourced from an illustrious European collection. Created in 1970 by Bulgari as a ring – at a time when Bulgari was undergoing some of its most significant transformations and emerging as the most influential and innovative Italian fine jewelery house in the world – the Bulgari Laguna Blu is three times as rare: it is an 11.16-carat Fancy Vivid blue diamond, one of the rarest gems in the world; it is a jewel signed by Bulgari; and is unmodified, meaning its current cut – manufactured in 1970 – could be further enhanced with modern cutting methods to free it up.

Sotheby’s Geneva auction has seen a surge with more than half (53.4%) of all lots selling well above their maximum estimate and virtually all lots sold fetching prices within or above their estimates (97%).
