Lustrous Bournonite specimen coming from a recent find in the Canutillos mine. It is composed of a group of metalic silvery twinned crystals of Bournonite with very well defined faces and edges and displaying the classic cogwheel shape. The piece is in excellent condition and shows a great aesthetic. A very good quality Bournonite specimen with nice twinnings. Watch video.
