JOHANNESBURG (miningweekly.com) – Russian diamond major Alrosa has discovered two large diamonds this week, one of which weighs nearly 110 ct and the other a 75 ct stone.
The larger of the two diamonds was recovered at the No 3 processing plant of the Mirny mining and processing division on Tuesday, and the other diamond was recovered two days prior to that at the No 14 processing plant of Aikhal mining and processing division.
Both rough diamonds are initially estimated as gem-quality. They are octahedron crystals with small inclusions, one of them with a straw-yellow tint.
“These large rough diamonds became presents for two anniversaries celebrated by the company - 60 years of diamond mining industry and 25 years of Alrosa,” the Russian firm said in a media statement on Wednesday.
The company added that it may name the two large diamonds.
