Sri Lankan authorities say the world’s largest star sapphire cluster has been found in a backyard – by accident, the BBC reports.
A gem trader said the stone was found by workmen digging a well in his home in the gem-rich Ratnapura area.
Experts say the stone, which is pale blue in colour, has an estimated value of up to $100 million in the international market.
The cluster weighs around 510 kilograms or 2.5 million carats and has been named the “Serendipity Sapphire”.
