These unpolished slabs of corundum-bearing rock from Hopedale, Newfoundland and Labrador, feature porophyroblasts and layers of granular corundum-sapphire-ruby ranging in colour from purple-plum, pink to fushia or magenta. The granular corundum is formed in a nice contrasting dark biotite-rich matrix. They are being sold by weight at around 50 cents CAD per gram.
These pieces make unique collector’s items, although they are not polished, they can be easily oiled or sealed with epoxy to maintain their vivid colours. They could also serve as beautiful lapidary rough for custom cabochons, rock tumbling or carving projects.
