The diamond company will not sale the unique ‘matryoshka’ diamond
ALROSA decided to leave an unusual matryoshka diamond in its collection of rare finds. The diamond with another crystal, freely moving inside, was mined at the Nyurba MPP for the first time in diamond mining history, Yakutia 24 TV channel reports with the reference to ALROSA.
The experts tell, that usually in such cases some minerals are replaced by others without a cavity formation. Diamonds may have medium-sized gas-liquid inclusions, but no voids of such a volume have ever been seen in crystals.
“Matryoshka diamond’s age may be more than 800 million years, according to the scientists. Despite the complex structure, it weighs only 0,62 carats (0,124 grams) and its maximum size is 4,8×4,9×2,8 millimeters,” tells the company.
It was found that the volume of the inner cavity is six cubic millimeters, and the volume of the inner crystal is 1,6 cubic millimeters with an estimated weight of 0,02 carats (0,004 grams). It has a tabular shape and dimensions of 1,9×2,1×0,6 millimeters.
Scientists at the ALROSA Geological Research Enterprise put forward various hypotheses on the diamond’s origin. To date, the most likely version is that both internal and external ones formed at the same time.
The collection of the company’s rare finds includes a skull-shaped and football-alike diamonds, found in recent years. The ALROSA collection of rare stones is not for sale.
