Shipwreck Emerald Sells for More Than $1M at Auction
The 5.27-carat stone, salvaged from the wreck of the Spanish ship Nuestra Señora de Atocha, blew pre-sale estimates out of the water.

Sotheby’s said Thursday the previously reported weight was an approximation derived from measurements, explaining that the stone was in a bezel setting when Mitzi brought it to the auction house, which did not allow its specialists to see its full breadth.
Prior to the sale, she allowed the auction house to remove the emerald from its mounting and have it evaluated by American Gemological Laboratories, which determined its exact carat weight.
