Polished stones - full range in stock "Narsarsukite"

Narsarsukite is a rare mineral. There are only 13 manifestations of this mineral in the world. In the USSR, narsarsukite was first discovered by V.I. Gerasimovsky in the 1930s in Lovozero near Mount Flora. Due to the fact that the manifestation was in a wooded area, it was later lost and rediscovered only in the nineties.

You can see narsarkurite stone (fees of the site owner) for sale and buy it in the Minerals of Russia online store.
