Solid cluster of intergrown nickelskutterudite (formerly called chloanthite) from the historic Schlema-Hartenstein District. Chloanthite is now regarded as an arsenic-deficient variety of nickelskutterudite or simply as a synonym for nickelskutterudite. Nowadays is very complicate find specimens of this size and quality. Complex crystals, bright, with faces... A piece highly valued by mineralogists. From the Type Locality. Only for "deep & dark collectors". It belongs from Joan Viñals and the Emili Nicolau collection (Barcelona).
