A pair of unmounted diamonds will be among the top lots Sotheby’s will offer at an upcoming Geneva auction, where it is set to fetch up to CHF 4 million ($4.8 million).
The stones are both cushion-shaped, D-flawless diamonds weighing 23.88 and 23.76 carats. They were cut from the same 108.36-carat rough diamond, Sotheby’s said last week. They make up one of the lots that will join the Mediterranean Blue, a modified brilliant-cut, 10.03-carat, fancy-vivid-blue, VS2-clarity diamond that is set to lead the May 13 High Jewelry sale. Though Sotheby’s gave it a price tag of “in the region” of $20 million, experts believe it could fetch as much as $30 million.
The auction will also feature pieces from famous designers such as Van Cleef & Arpels, Graff, Bulgari, and Cartier.
