A choice specimen of very rare rouaite with even rarer buttgenbachite and cuprite from Tenke Mine, Congo - Kinshasa. Rouaite is an uncommon secondary copper nitrate. Buttgenbachite is a very rare secondary copper mineral too. It displays platy rouaite with lustrous faces and a rich blue-green color. Blue buttgenbachite grows above. Small cuprite crystals form the base. Some side contacts. On acrylic base.

Excellent rouaite-buttgenbachite combo!
