A very heavy specimen of solid skutterudite, from a CLASSIC and important locality for the species! These are old specimens, some to the 1800s, and now rare on the market. Technically this former species is now regarded as an arsenic-deficient variety of Nickel-Skutterudite or simply as a synonym for Nickel-Skutterudite.. In any case, this is an excellent example of the nickel species, well crystallized, and a beautiful display quality miniature. The complex form of these crystals, and their bright luster, mark them as German apart from modern finds in Morocco.
