Diamond producer Alrosa has said that it has discovered a 236-carat rough diamond of "intense yellow-brown colour" at its remote Ebelyakh mine on river Anabar in the extreme northeastern region of Yakutia, Russia.
"This is the largest natural colour rough diamond ever found in Russia," Alrosa said. According to preliminary estimates, the diamond is 120-230 million years old.
The precious discovery was made by workers, not far from shores of Laptev Sea and some 1,211km north west from Yakutsk.
The mine belongs to Diamonds of Anabar, part of ALROSA Group.
The rough diamond is of deep amber colour, its dimensions are 47x24x22 mm.
The decision hasn’t yet been made as to whether it’ll be sent to Alrosa’s in-house cutting and polishing division, or sold rough.
