A Sri Lankan gem trader is selling the world’s largest blue star sapphire.
The egg-shape stone weighs 1,404.49 cts. and has been authenticated as the largest of its kind by the Gemological Institute of Colombo (GIC).
“We can’t put a price on something like this,” Ashan Amarasinghe, a gemologist at the GIC told Agence France-Presse. “It is so rare, and unlike other, smaller sapphires, this is not a stone that can be replaced. This is something only collectors or museums can afford.”
The BBC reports that the seller expects the stone to sell for $175 million at auction; Agence France-Presse puts the price at $300 million.
The stone was found in Sri Lanka’s central region of Ratnapura, according to reports.
“I have lived in affluence, but now I feel even more blessed,” said the owner, who asked to remain anonymous due to the value of the stone. “This [find] has not changed my lifestyle. But, I feel thrilled to be the man owning this gem. It is good for the ego.” He purchased the stone in September 2015 for an undisclosed sum.
The BBC reports that the owner has named the stone the Star of Adam, after the Muslim belief that Adam arrived in Sri Lanka after being sent away from the Garden of Eden.
Details of the auction have not yet been announced.
