Russia’s ALROSA has discovered a 102.85-carat diamond with a moderate yellowish hue at its Jubilee kimberlite pipe that is thought to be worth more than $480,000.
The company’s Aikhal Mining and Processing Division found the octahedral-shaped stone in September which contains small olivine, graphite and sulfide inclusions, it said in a statement on its website. The unit digs precious stones at the Jubilee and Komsomolsky open pits and the Aikhal underground mine.
The discovery last month follows a 253.16-carat rough diamond — worth an estimated $1.5 million to $2 million — that Aikhal Mining and Concentration Mill found at the Jubilee pipe two years ago. At the time the company cited technological advancement at its production facility behind its success in recovering exceptionally large stones and avoiding breakages. Six diamonds with weights ranging from 50 to 120 carats have been recovered from the Jubilee pipe this year, the Russian company said.
