Alrosa Finds 158 Carat Diamond



Earlier this month, Russian diamond miner Alrosa uncovered a diamond that is one for the books—the gem weighs a whopping 158.2 cts.

Alrosa describes the stone as “a natural crystal roundish in shape, transparent and having prominent facets on one of the sides. The central part is clean, with no visible defects; there are inclusions of dark color, cracks, and a technical chip in the peripheral area.”

The diamond’s size is 35 x 22 x 22 millimeters.

Alrosa expects the stone to sell for $1.5 million, if auctioned.  

“If cut, this rough diamond may produce several polished diamonds having high quality characteristics, and each of them may be worth hundreds of thousands of U.S. dollars,” the diamond producer added.
