ALROSA extracts the largest yellow rough diamond this year

11 october 2018
JSC Almazy Anabara, a subsidiary of the world’s largest diamond mining company ALROSA, extracted large 28.59-carat rough diamond of deep greenish-yellow hue. Following the assessment, the color of the stone is defined as the rare Fancy Intense Yellow.
Today, it is the largest yellow rough diamond mined at ALROSA’s deposits since the beginning of 2018.
The diamond was discovered at Ebelyakh placer deposit in July; it has dimensions of 11.40 x 19.00 x 17.50 mm. This is a chip of the crystal with insignificant colorless inclusions on the surface.

“The extracted stone is our new unique discovery. Fancy colorsare very rare in nature. This stone is also unique, because nature seemed to have prepared it for cutting and in advance gave it a pear-like shape. United Selling Organization of ALROSA and the company’s cuttingdivision DIAMONDS ALROSA have yet to study the diamond and decide whether to auction it as a rough or to cut itinto polished diamond. However, even now one can say this is a worthy specimen for replenishing our collection of colored diamonds,” Evgeny Agureev, the Member of the Executive committee, Director of the United Selling Organization of ALROSA, said.
Almazy Anabara is traditionally the leader in the number of fancy-colored stones. In 2017, Almazy Anabara also extracted a unique 27.85-carat pure pink diamond– the largest pink stone in ALROSA’s history, and a large 34.17-carat vivid yellow diamond.
ALROSA plans to focus its cutting division on the processing of large and colored diamonds and the subsequent sales. Starting 2018, ALROSA sorts colored diamonds according to a new technology, that includes almost all hues and color grades. Most of these diamonds are processed by DIAMONDS ALROSA - the company's in polished branch.
Today, ALROSA produces at least 7 thousand carats of colored diamonds per year. In September, the True colors auction started in Hong Kong, where ALROSA showcased collection of 250 diamonds of different shapes and hues. The company plans to run such auctions regularly.
