Russian diamond mining giant Alrosa recently recovered a "unique" gem-quality rough diamond weighing 98.8 carats from the Zapolyarnaya kimberlite pipe, which is the part of the Verkhne-Munskoye diamond deposit. Alrosa officially launched the Verkhne-Munskoye diamond deposit on October 31, 2018, and it has now yielded two large gem-quality stones in the first couple months of operation, having produced a 51.49 carat gem-quality diamond last fall. The output of the Verkhne-Munskoye deposit is expected to be about 1.8 million carats of rough diamonds per year, with reserves are sufficient to continue mining for more than 20 years - until 2042.
The gem has an octahedral shape and is of gem-quality with inclusions in the peripheral and intermediate zones. The rough diamond is transparent with a visible yellow shade. "This is the second major find since the launch of the deposit last October, said Evgeny Agureev, Member of the Management Board, Director of the United Selling Organization at ALROSA. "It allows us to speak about the great potential of the Verkhne-Munskoye deposit. Not every kimberlite pipe regularly brings large diamonds over 50 carats. Especially when it comes to such a large crystal, like this one - weighing almost 100 carats. Despite some inclusions, it is clear that this is a high quality stone. After a detailed study and evaluation, I believe it will be transferred to Diamonds ALROSA cutting and polishing division."
