Uranite

Uranite, a rather rare mineral which occurs chiefly in Cornwall, Saxony, Bohemia, and Belgium. It crystallizes in the tetragonal system, and forms clusters, emerald-green, semi-transparent crystals, rather soft, and possessing a specific gravity of 3.5. It consists chemically of the phosphate of copper and uranium, a lime uranite also occurring, in which the copper is largely or wholly replaced by calcium.
