A new world record has been set per carat for any gemstone. Recently, a rare 7.03 carat blue diamond that was unearthed in the Cullinan mine in South Africa went on auction for a record of approximately $10 million. The gem owes its vivid colour to boron, a chemical that brings out the blues.
The blue diamond is the rarest of all diamonds, and this recent auction is said to have set a new world record price for a fancy, vivid blue diamond.
The new owner of the blue diamond has the right to name the stone, which is mounted in a platinum ring. This diamond will surely last forever.
