Offbeat combo specimen of Tetrahedrite crystal with alteration by Azurite and Malachite with minor Cuproromeite from El Coriellu mine, Spain. The Tetrahedrite crystal of 10mm forms an excellent focal point at the top of the white base. It has sharp tetrahedral shape. Green Malachite and blue Azurite alternate the faces of the Tetrahedrite. Very rare Cuproromeite, originally named Partzite, replaces partially the Tetrahedrite crystal. It has olive–green color. In good condition - some small contacts. On acrylic base.

Superb!
