Sculpture of intergrown black Sphalerite crystal and Pyrite. Displays well shaped black Sphalerite tetrahedron with good luster. It is sharp with some cavernous formation on the faces and perfect geometry. Above are growing yellow Pyrite crystals. They are well isolated and lustrous. The contrast is very good.
