Item number: 11746

A kind of botryoidal aggregate composed of many 1-3mm sphalerite crystals. The spahlerites are brown and have pyrite (I think) oriented on the edges of the faces. The matrix is massive sulphides, mostly pyrite and, it appears tetrahedrite coursing through it. Interesting high grade!
