Pentlandite

Pentlandite in Pyrrhotite specimens from the Sudbury Basin in Canada. Pentlandite may contain only small amounts of Ruthenium, but it’s one of the only minerals you can find on the internet to represent a sample of the rare element as it’s found naturally, as these specimens came from the same mine which provides most of the 30 tons of Ruthenium which are mined annually!

With each order you’ll receive one (1).
