Alrosa unearths 102-carat diamond

Mining company Alrosa has recovered a large diamond of 102.85 carats from its Jubilee kimberlite pipe.

The diamond was extracted by the company’s Aikhal Mining and Processing Division (MPD) at processing plant No.14.

The firm says diamond has an octahedral shape; it is transparent, with moderate yellowish hue. There are small olivine, graphite and sulphide inclusions in this crystal.

According to experts at Alrosa’s Diamond Sorting Centre, the stone could fetch as much as $480,000 (£312,400) at auction.

The Jubilee pipe is known for its large finds, with six diamonds ranging from 50 to 120 carats recovered from the deposit in the year to date.
