ALROSA reported that it recovered a 98.8-carat rough diamond on February 17 at the Zapolyarnaya kimberlite pipe, which is the part of the Verkhne-Munskoye diamond deposit. The gem-quality octahedral stone has a visible yellow shade and has inclusions in the intermediate and peripheral zones.
ALROSA United Selling Organisation (USO) Director Evgeny Agureev commented, “This is the second major find since the launch of the deposit last October. It speaks of the great potential of the Verkhne-Munskoye deposit. Not every kimberlite pipe regularly produces large diamonds over 50 carats — especially large crystals like this one, weighing almost 100 carats.”
He added, “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 the Diamonds ALROSA cutting and polishing division.”
The first large gem-quality diamond was mined here in the late fall, shortly after the official launch of the deposit on October 31, 2018. That stone weighed 51.49 carats.
The Verkhne-Munskoye diamond deposit is located in the west of Yakutia, 170 km from the town of Udachny. At present, four kimberlite pipes at the deposit have been explored — Zapolyarnaya, Deimos, Novinka, and Komsomolskaya-Magnitnaya. It is today the project with the highest investment by ALROSA — RUB 16 billion ($243.3 million) have been spent to date.
