  • Prehnite's color varies from light green to yellow, but also colorless, blue, pink or white. In April 2000, rare orange Prehnite was discovered in the Kalahari Manganese Fields, South Africa. Prehnite is mostly translucent, and rarely transparent.
  • Though not a Zeolite, Prehnite is found associated with minerals such as Datolite, Calcite, Apophyllite, Stilbite, Laumontite, and Heulandite in veins and cavities of Basaltic rocks, sometimes in Granites, Syenites, or Gneisses.
  • It was first described in 1788 for an occurrence in the Karoo Dolerites of Cradock, Eastern Cape Province, South Africa. It was named for Colonel Hendrik Von Prehn (1733–1785), commander of the military forces of the Dutch colony at the Cape of Good Hope from 1768 to 1780.
  • Prehnite is used as a gemstone. Extensive deposits of gem-quality Prehnite occur in the Basalt tableland surrounding Wave Hill Station in the central Northern Territory, of Australia.
