Fine petalite is rare and fragile. For this reason it is only occasionally cut for the collector. Crystals are transparent, colourless or white, occurring as tabular or columnar prisms with a glassy appearance. Massive petalite is more common, cut in cabochon.

Petalite is mainly found in Elba (Italy), Brazil, Australia, Sweden, Finland, USA, Zimbabwe and Namibia.
