Russian diamond miner Alrosa has unearthed a large 34.17 ct. yellow diamond, the largest fancy-colored rough it’s extracted this year.

The rough diamond, from the Ebelyakh alluvial deposit, measures 20.17 millimeters by 19.65 millimeters by 15.1 millimeters. It is a transparent intense yellow crystal that shows a small inclusion. The company said it expects it to receive the top color grade, fancy vivid.

“This year Alrosa has already hit the record in the number of large fancy-colored stones,” said the director of Alrosa’s United Selling Organization, Evgeny Agureev, in a statement. “We used to extract fancy-colored rough diamonds over 10 carats once a year on the average. This year, we have already recovered several large fancy-colored diamonds, and this 34.17-carat yellow stone is the largest one so far.”

Earlier this year, Alrosa also extracted a 27.85 ct. pure pink diamond—the largest pink stone in its history.
