With an estimate of CHF 10 million to CHF 15 million ($11 million to $16.5 million), the cut-cornered rectangular modified brilliant-cut, VVS1-clarity gem is the fourth-largest intense-pink diamond ever to appear at auction, according to Benoît Repellin, Phillips’s worldwide head of jewelry.

The 110-lot sale, Geneva Jewels Auction: ONE, will take place at the Swiss city’s Hôtel La Réserve and feature a number of impressive diamonds, as well as a curated selection of untreated colored rubies, emeralds and sapphires.
