ALROSA To Auction 11-Ct Deep Purple-Pink Diamond In Hong Kong

ALROSA, the world’s largest diamond producer by output in carats, will hold its first “True Colour” auction of colored polished diamonds during the upcoming Hong Kong Jewellery & Gem Fair.

The collection includes 250 polished diamonds of various shapes and colors – purple, pink, orange and vivid-yellow stones with GIA certificates – some of them of very rare shades. ALROSA said it will be the first time it has presented such a large quantity of large colored diamonds.

The star of the show will be an 11-carat fancy deep purple-pink cushion cut diamond which it says is the largest diamond of this color ever certified by the GIA.

“It took more than a year to prepare the collection," said ALROSA deputy CEO Yury Okoemov.

ALROSA will auction the stones via a special electronic platform.

ALROSA is sorting its colored rough diamonds into 19 color groups. Most of them are polished by ALROSA cutting subdivision.
