The diamond world could be rocked with a new record later this year when this 8.41-carat purple-pink diamond goes up for auction at Sotheby’s Hong Kong Magnificent Jewels and Jadeite Autumn Sale.
The stone, originally mined by De Beers, weighed in at 19.54-carats in its rough form. It will tour around the world with stops in Singapore, Taipei, New York, London, Geneva and Hong Kong leading up to the October 7th auction.
At the auction, the pear-shaped stone could sell between $12.8 million and $15.4 million (USD). The per-carat selling record for a pink diamond was set in 2009 when a 5-carat stone sold for $2.1 million/carat. If this purple-pink stone goes beyond estimate and sells for over $18 million, that record could be in jeopardy.
The largest overall sale for a pink diamond was for the Graff Pink Diamond, a 24.76-carat, Fancy Intense pink diamond that sold at auction in 2010 for $46.2 million or $1.86 million per carat.
In the years since those two massive pink diamond sales, the value of pink diamonds has continued to increased in value. A situation that will only continue as the world’s main source of pink diamonds, the Argyle mine in Australia is expected to close by 2019.
