It took just a few minutes for the bids to reach 21 million Swiss francs ($22.9m) after the marble-sized stone came up in an online auction through Sotheby's, with the final buyer remaining anonymous.

Sotheby's auctioneer Benoit Repellin called the diamond a "wonder of nature" and added that prices for the pink gems are going up as they become increasingly rare.

The Spirit of the Rose was faceted from a 27.85-carat stone found in 2017 by diamond mining firm Alrosa in Russia's Sakha republic in northeast Siberia.

It took about a year of painstaking work to cut the finished diamond to shape while preserving its pink colour.

Pink diamonds are the rarest of the precious gems and the most in demand on the global market.

The world record for a pink diamond dates back to 2017, when a stone known as the CTF Star Pink was sold in Hong Kong for $71.2m.

Five of the 10 most expensive diamonds ever sold have been pink, Sotheby's said, with all sold within the past decade.

Just this month, the biggest pink diamond mine in the world stopped production, as Australia's Argyle deposit that accounted for more than 90 percent of global supply was exhausted.
