The Russian mining company, ALROSA recently announced the discovery of a 102.85-carat diamond that is worth more than US$480,000. The discovery was made at its Jubilee Kimberlite pipe by the company’s Aikhal Mining and Processing Division. This division of the company also digs precious stones from the Jubilee and Komsomols open pits and the Aikhal underground mine.
The octahedral shaped diamond with a slight yellowish hue was mined in September. According to the statement released by ALROSA, it has been found that the diamond contains small olivine, graphite and sulfide inclusions.
The mining company expressed its happiness in discovering the large diamond and said that it was largely due to the technological advancements made in mining.

The diamond was also mined from the Jubilee pipe by the Aikhal Mining and Concentration Mill. The company has also mined six diamonds weighing between 50 and 120 carats from the Jubilee pipe last year.
