The 92.15-carat diamond, which was mounted in a necklace, achieved $162,611 per carat, falling within its pre-sale estimate of $14.1 million to $20.2 million. The piece, dubbed “La Légende,” was a creation of Boehmer et Bassenge, a high-end maison launched last year and named after 18th-century Parisian jewelers Charles Boehmer and Paul Bassenge.
Other sales at the auction included a ring set with diamonds and an oval-cut, 15.03-carat ruby, which garnered $12.9 million. Separately, a cushion-shaped, 7.97-carat, fancy intense blue, VS1-clarity diamond went for $12.7 million, or $1.6 million per carat.
The Magnificent Jewels auction recorded total proceeds of $95 million (CHF 93.1 million) including buyer’s premiums. It came a day after rival Sotheby’s sold $151.5 million of jewelry at its Geneva event, headlined by a pair of earrings that fetched a record $57.4 million, or $2.9 million per carat.
