The Guinness-certified world’s largest sapphire, weighing in at 31,308 cts., making it the size of a dinner plate, is up for sale, says owner Ophir Collection.
A release from the company did not say where and when it would be sold, but spokesperson Kris Astor suggests the sapphire, and others in the accompanying 40-piece collection, may be sold via private auction. She declined to provide an estimate, saying it is difficult to value some of the stones.
