World’s largest sapphire cluster worth $100M found in backyard in Sri Lanka

A massive sapphire cluster worth as much as $100 million has been unearthed by workers digging a well in the backyard of a Sri Lankan home, authorities said.

The 2.5-million carat gem, which is believed to be the world’s largest sapphire cluster, was discovered behind the home of a third-generation gem trader in Ratnapura, the BBC reported. “The person who was digging the well alerted us about some rare stones. Later we stumbled upon this huge specimen,” the owner, who only wanted to be identified by his last name Gamage, told the outlet.
