The world's largest “D coloured” diamond.


World’s largest ‘D coloured’ polished diamond unveiled in Dubai


DUBAI – The world’s largest “D coloured” diamond was unveiled in Dubai on Thursday (September 26) during the Dubai Diamond Conference.

Dubai-based diamond trading company, Nemesis International, said the emerald cut diamond is certified by Gemmological Institute of America (GIA).

The diamond comes from the world’s most valuable rough diamond “The Constellation” with a weight of 812.77 carats and record purchase price of $63 million.

The evaluation, maping and polishing process took over 18 months to complete, and was mainly processed and completed here in the UAE by Almas Diamond Services, a sister company of Nemesis International. The final result was 8 polished stones, including a main stone of over 313 carats and emerald cut stone of over 100 carats.

This was the first time that craftsmen in UAE have dealt with a diamond of this size and importance.

Dubai’s diamond industry has grown into one of the largest in the world, with over Dh92 billion ($25 billion) traded through the emirate in 2018 alone and Dubai now standing as a leading global diamond center on par with New York, Antwerp and Mumbai.

“We are extremely proud to present the rarest D coloured diamond, which was cut and polished over the last 18 months here in the UAE by our sister company, Almas Diamond Services. We are keen to build a legacy for these diamonds, in recognition of the emergence of the diamond industry in the UAE on the world stage,” said Konema Mwenenge, CEO of Nemesis International.
