The auction house will present its Magnificent Jewels sale in Hong Kong July 10, featuring more than 200 lots.
Leading the sale is a pair of fancy vivid colored diamond rings in the shapes of hearts (to be sold as separate lots)—a 5.04-carat fancy vivid blue Type IIb diamond ring, estimated to garner between $7.7 million and $9.7 million, and a 4.49-carat fancy vivid pink internally flawless diamond, which could go for between $7.5 million and $8.8 million.
There will also be a few other heart shapes in the sale, including the pair of unmounted diamonds seen below. Both weigh 10.51 carats each, and the two are expected to sell for between $1.8 million and $2.1 million total.
Magnificent Jewels will also include pieces from iconic houses, like a pair of Colombian emerald and diamond earrings from Harry Winston that could sell for as much as $1.9 million, a famed “Zip” necklace from Van Cleef & Arpels that could go for up to $451,000, and an Art Deco brooch from Cartier’s famous Tutti Frutti series.
