Bournonite small cabinet The Brookite shows a deepA wonderful single crystal of Bournonite showing BRIGHT metallic luster, and superb form. Crystals with high luster from this mine are not common, even in toenail small miniature sized crystals like this one. The piece is complete all the way around and damage free, save the base where it came off the host rock. It certainly could be classified as a cogwheel piece, as it is twinned, and does have some small cogs around the edges. Specimen # BOL711B25
