Diamond is said to be every girl’s best friend, for this enticing precious stone is quite an expensive piece of jewel to buy. While learning the chemical and physical formation of diamonds, every child has had a curiosity to understand its formation, structure and manufacturing. Indeed, it is a herculean task to carve a diamond either for commercial use or personal.

Let’s learn about the current discoveries and then about the science behind diamonds!

Recent discovery on the diamond

The largest gem-quality diamond of 552-carat stone has been found in Diavik Diamond Mine in Canada’s Northwest Territories near the Arctic Circle.

Currently, the diamond is exhibited at a Smithsonian museum in Washington along with the iconic Hope Diamond

Specifications of diamond

Colour: Yellowish

Size: 33.74mm x 54.56mm (approximately the size of a small chicken egg)

Weight: 552.74 carats

Price: USD 1.3 million

This diamond is nearly three times the size of the previous record holder, a 187-carat gem called the Foxfire, Dominion Diamond Mines said.

“A diamond of this size is completely unexpected for this part of the world,” said Dominion, 40 percent owner of the mine. It called the find “astonishing”.

Dominion said the rough stone — with some abrasion markings on its surface due to “the difficult journey it underwent during recovery” — would be polished and cut by a master cutter before its ultimate value can be determined.

Largest diamond in the world

The name of the largest diamond is the Cullinan, which was unearthed in South Africa in 1905.

It was ultimately cut into nine major stones and 96 smaller ones.

How is a diamond formed?

The formation of a diamond is not at all difficult to understand

  • Diamonds come out from the earth’s mantle to the surface in form of volcanic magma that solidifies into rock
  • These precious stones can also be found under pressures and temperatures at the site where meteorites have landed from the space on the surface of the earth
  • Actually, the debris from the death of a star forms stardust which is a relatively young diamond if compared with 50 to 1,600 million years old diamonds found in the mantle.
