described the diamond as “Gem Quality” and estimated its value range from $1.5
million to $2 million. The stone was produced from the deep Yubileynaya
(Jubilee) diamond pipe, at Factory No. 14 of Alrosa’s Aykhalsky mining
facility. It measures 42mm x 26mm x
28mm. The crystal is transparent, with a yellow hue and there are small
graphite-sulfide inclusions along the periphery.

explained that recent technological advancements made at the production
facility have improved recoveries and reduced breakage of exceptionally large
stones.
