(Kitco News) - The world’s top diamond producer by output, Alrosa, has surpassed its record number of large colored diamonds unearthed in a year, with the latest discovery being a 34.17-carat yellow diamond — the biggest find by the company to date.

“This year, Alrosa has already hit the record in the number of large fancy-colored stones,” said Evgeny Agureev, director of the United Selling Organization Alrosa. “We used to extract fancy-colored rough diamonds over 10 carats once a year on the average. [In 2017], we have already recovered several large fancy-colored diamonds, and this 34.17-carat yellow stone is the largest one so far.”

The discovery was made by Alrosa’s affiliate Almazy Anabara at the Ebelyakh alluvial deposit in the Republic of Sakha (Yakutia), located in Far Eastern Russia.

The measurements of the precious gem are 20.17 by 19.65 by 15.1 mm.

It is described as “a transparent intense yellow crystal with a small inclusion in the intermediate zone,” according to a press release.

Russia’s diamond company plans to send the stone to Moscow before the end of October for further assessment.

“The Company’s specialists are still to study the stone more in detail, but we can say in advance that it is fancy vivid yellow, which is very rare and highly valued,” Agureev added.

Alrosa has had a very lucky year. In September, the company announced that it made history with a discovery of a massive 27.85-carat rough pink diamond — the most expensive precious stone in the company’s collection. 

And in June, Alrosa revealed it recovered a 62.75-carat diamond from its very fruitful Jubilee kimberlite pipe. The precious stone was described as transparent with a light-yellowish tint and an octahedron shape. 

Alrosa, accounts for more than 29% of global diamond production in terms of carats. In 2016, the company said it produced 37.4 million carats of rough diamonds, with plans to ramp up production to over 41 million carats annually by 2019.
