Krutovite (rare Ni-arsenide) Vajdak Coll.

Item Description

All sides of the matrix host metallic-gray nodules, to about 6 mm, of the rare Ni-arsenide krutovite, discovered in 1975. This rich and excellent specimen is very rare from the Svornost Mine and is in the same Type Locality District. In fact, one side might be a solid krutovite vein or some other arsenide/sulfide. Rare and rarely available. Not pretty to look at, but very rare for the species. Ex Josef Vajdak Collection, a noted Czech specialist.
