The largest diamond to have ever been found in North America was recently unearthed from a mine in Canada’s frozen north by Dominion Diamond Mines and Rio Tinto Group. The yellow diamond, which weighs 552 carats, was recovered at the Diavik Diamond Mine, located in Northern Canada about 135 miles south of the Arctic Circle. The Diavik mine does produce some very high quality diamonds, but is not known for the huge gems usually found in African mines.

According to Bloomberg News, Dominion Chief Executive Officer Shane Durgin said the diamond is gem quality, meaning it is suitable for jewellery, but gave few additional details that can help determine its value.

“We can label it fancy yellow, but beyond that, due to its rough nature and the abrasions received through the processing facility, that’s all we can comment on. It’s very hard to give a ballpark estimate. It all depends on, again, the cutting and the resulting stone it ends up,” Bloomberg quoted Shane Durgin as saying in an interview.

Dominion Diamond Mines revealed the diamond was unearthed in October and that it far surpasses the previous record held by the Diavik Foxfire at 187.7 carats, which was also recovered at the same mine in 2015.

“This incredible discovery showcases what is truly spectacular about Canadamark diamonds. The color and texture of the diamond are a unique example of the journey that natural diamonds take from their formation until we unearth them. Our Diavik Mine has produced some of the most beautiful diamonds in the world, and this one certainly tops the list,” Kyle Washington, chairman of Dominion Diamond Mines, said.

It was further revealed that the diamond, which has a unique colour, texture and structure, will not be sold in its rough form and may be studied further, and Dominion will select a partner in the coming weeks who will cut and polish the stone.

The size and highly technical nature of this stone means that only a handful of master cutters in the world are qualified to polish it, ensuring that the stone’s beauty, color and brilliance are maximized. Dominion expects to achieve a significant main stone once the diamond is polished, that will be Canadamark certified.

As the diamond is still undergoing evaluation, it is too early to determine its ultimate value, but it is said to be the size of a chicken egg.
