Set your sights on an extremely rare diamond that is going under the hammer at Sotheby's Hong Kong next month

A jaw-dropping 88.22-carat, flawless D-colour diamond is set to lead Sotheby’s Hong Kong Sale of Magnificent Jewels and Jadeite on April 2. It’s estimated to fetch a staggering HK$88-100 million (S$15-17 million), and is one of only three oval diamonds that weigh over 50 carats to appear at auction in living memory.

“When you think that one ton of mined earth yields less than a carat of diamond, and that high-quality diamonds over 10 carats are a rarity, the discovery of a 242-carat rough, of gem quality and exceptional size, is nothing short of a miracle,” says Patti Wong, chairman of Sotheby’s Asia, before adding that the oval gem is “a wonder of nature, a masterpiece resulting from man’s ability to shape the hardest material on earth into an object of ultimate beauty”.

Finding a rough diamond that’s big enough to fashion a stone of over 80 carats is extremely rare. Originally a 242-carat rough gem from Botswana, this dazzling piece was worked on for months before being cut into 88.22 carats—the number eight is a symbol of perfection, often associated with prosperity, in Asian culture.

Other auction highlights include a 20-carat diamond ring, with an estimated value of S$1.9-2.7 million, and a ruby and diamond bracelet weighing a total of 40 carats.
