A marvelous and unusual specimen of tetrahedrite, chalcopyrite and covellite from 2nd Sovetskii Mine, Dalnegorsk, Russia. The tetrahedrite crystals have a sharp shape with a good luster. They grow with yellow chalcopyrite. Iridescent in electric blue and purple covellite adds a nice colorfulness. The specimen is complete all over. In excellent condition. On acrylic base.

Neat!
