The Eternal Pink, mined by De Beers at the Damtshaa mine in Botswana is expected to fetch more than $35 million at the upcoming Sotheby’s HK auction, potentially breaking records as the most expensive price per carat ever to come to market. The estimated price per carat for The Eternal Pink is $3.3 million, giving it a chance to challenge the record set by The Williamson Pink Star, which was sold at Sotheby’s Hong Kong in 2022 for $5.2 million per carat. That gem was bought by a private collector based in the US for $57.7 million.
