In the official ALROSA press release, director of the United Selling Organization ALROSA Evgeny Agureev commented,
"This year for ALROSA has already hit the record in the number of large fancy-colored stones. 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 by 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."
