Geologist Yuri Erokhin gives regional newspaper scoop on mariinsky gem

Yuri Erokhin, a researcher at the Institute of Geology and Geochemistry, recently gave an interview on the recent discovery of a new gem named mariinsky.

The 2012 reveal of the gem in the Urals led to much speculation and misinformation regarding the material, leading Erokhin--who has researched the material, along with Leonid Pautov, Mikhail Popov, Vera Hiller and Vladimir Karpenko--to sit down for the interview with regional newspaper Oblastnaya Gazeta.

Erokhin said the gem may currently only have value to scholars and collectors rather than jewelers, for a number of reasons: the gem must be suitable for faceting, and its cost could be up to five times that of a diamond of the same size because of its rarity and color--the gem's crystals are just one millimeter in size, according to Oblastnaya Gazeta.

Additionally, Erokhin said the gem does not have the properties of a diamond, as had been previously reported; the gem is comprised of the mineral chrysoberyl alexandrite, giving it an emerald green color, Oblastnaya Gazeta reports.

The first samples of the mineral were described in 1937, but only recently have researchers been able to prove the gem's uniqueness, and only recently has the gem garnered the attention of the media.

In 2011, it was admitted to the International Commission on New Minerals, and last December, the group published its research results in a major scientific journal, according to Oblastnaya Gazeta.
