An extremely rare 15.38 carat pear-shaped pink diamond – called the ‘Unique Pink’ – sold for $31.6 million at Sotheby’s in Geneva on Tuesday, making it the most expensive fancy vivid pink diamond ever to sell at auction.
The spectacular diamond, set in a simple ring, sold to an Asian private buyer who bid for the rare gem over the telephone. A Sotheby’s spokesperson said they were not yet able to reveal the buyer’s identity.
