A 15.1-carat fancy vivid blue diamond is projected to be auctioned for a whopping $48 million — the highest estimate ever for a blue diamond.
The gemstone — known as the De Beers Cullinan Blue — will be the largest fancy vivid blue diamond to appear in an auction when it is offered up at Sotheby’s Hong Kong.
The jewel was first discovered in April 2021 at the South African Cullinan mine, which, according to Sotheby’s, is one of the very few places in the world to discover rare blue gems.
“Blue diamonds of any kind are rare on the market, but this is the rarest of the rare; nothing of remotely similar caliber has appeared at auction in recent years,” said Chairman of Sotheby’s Asia Patti Wong.
