"When the stone was brought to me I suspected that it might be the world's largest blue star sapphire. So I took a risk and bought it."
It's not clear how much he paid for the blue star sapphire, which gets its name from the distinct, star-like mark found near its centre.
The owner has named the gem the Star of Adam.
