Anglesite gets its name from a deposit locality: Anglesey, an island in Wales. Anglesite forms several types of crystal habits: tabular, prismatic, pseudorhombohedral, or pyramidal. They resemble those of barite and celestite. Prized by collectors for its strong dispersion, anglesite is often colorless to white, grayish, yellow, green or blue.
