ALROSA has found a 34.17-carat yellow diamond which is the largest fancy-colored rough diamond extracted by the company this year.
The rough diamond, extracted from the Ebelyakh alluvial deposit, measures 20.17 х 19.65 х 15.1 mm. It is a transparent intense yellow crystal with a small inclusion in the intermediate zone, the miner said.
Before the end of October, it will be delivered to the United Selling Organization ALROSA (USO ALROSA) in Moscow, where the company specialists will give it a more detailed and accurate assessment.
"This year for ALROSA has already hit the record in the number of large fancy-colored stones," said the director of the United Selling Organization ALROSA Evgeny Agureev. "We used to extract fancy-colored rough diamonds over 10 carats once a year on 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.
"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. The stone will become a worthy addition to our collection of large rare-colored diamonds that we are forming and will bring to the market."
Earlier this year, ALROSA also extracted a 27.85-carat pure pink diamond - the largest pink stone in its history.
