Leading the online-only “Jewels Online: Summer Sparkle” auction at Christie’s is this 24.45-carat D color, internally flawless, Type IIa heart-shaped diamond, estimated at $1.6 million-$2.6 million.

New York—Christie’s is dedicating its online-only summer jewelry auction to diamonds, and leading the way is a big heart shape.

“Jewels Online: Summer Sparkle,” held now through Aug. 18, features a wide variety of colorless and fancy color diamonds, including pink, orange, green, brown, and yellow, some of which are being offered without reserve.

The highlight of the sale is a 24.45-carat D color, internally flawless, Type IIa heart-shaped diamond pendant that’s estimated to sell for between $1.6 million and $2.6 million, making it the highest valued jewel ever offered in an online-only auction at Christie’s.

Last year, a 28.86-carat D-color, emerald-cut, VVS1 Type IIa diamond set the record, garnering $2.1 million at Christie’s Jewels Online sale in June.

Its sale comes at a time when colorless diamonds have been topping expectations at auction.
