New large diamond found at

Alrosa’s Verkhne-Munskoye deposit

Alrosa, the world's largest diamond mining company, extracted a large rough diamond from the Zapolyarnaya pipe of the Verkhne-Munskoye deposit. The gem-quality rough diamond was mined in July. Its weight is of 63.15 carats. The crystal has an octahedral shape with small chips on the edges and tops. The mined diamond is transparent with a yellow hue.

In March, Alrosa conducted an experiment to clarify the diamondiferous nature of the north western part of the Zapolyarnaya pipe at the Verkhne-Munskoye deposit. 

In 5 days, we extracted 239 large (over 8 carats) diamonds from the Zapolyarnaya pipe, or more than 3.5% of the number of diamonds extracted during the experiment. These figures exceed the data for other pipes of the Alrosa Group.

The first large (over 50 carats) diamonds of the Verkhne-Munskoe deposit were a 51.49-carat crystal, mined immediately after the official launch in autumn 2018, and a unique 98.8-carat diamond. 

Both stones were recognized as gem-quality diamonds. Verkhne-Munskoye diamond deposit is located in the west of Yakutia, 170 km from the town of Udachny. 

At present, four kimberlite pipes have been explored:  Zapolyarnaya, Deimos, Novinka, and Komsomolskaya-Magnitnaya. Today it is the largest investment project of Alrosa.
