A large sapphire with an estimated value of at least $100 million has been discovered in Sri Lanka, and now the man who made the purchase will have to decide what he’ll do with it next.

Weighing 1,404.49 carats, the blue, oval-shaped gem is about the size of your palm, according to Reuters. The stone was mined from the country’s Ratnapura district and has been verified by the National Gem and Jewellry Authority of Sri Lanka as the largest sapphire in the world, the report added.

Now, he must decide whether he will sell the historic find or put it on display in a museum. It’ll be a tough decision either way – some gemologists said the sapphire could sell for up to $175 million, reported.

He told the BBC that he purchased the stone, suspecting that it might be the largest ever discovered, but did not disclose the price he paid for it. Once gemologists took a closer look, they confirmed that it was slightly larger than the previous world record sapphire, which weighed 1,395 carats.

The sapphire was named “Star of Adam” because of a Muslim belief that when Adam was sent away from the Garden of Eden, he went to Sri Lanka, the BBC report also said.
