Prehnite~

Hendrik von/van Prehn is credited with discovering the mineral in 1774 at the Cape of Good Hope in South Africa. Von Prehn was a governor of Cape of Good Hope (1779-1780) until he was dismissed. He was a naturalist and mineral collector who brought the first specimens of his namesake mineral to Europe. It is unknown how the mineral came to the attention of Werner. A considerable mystique and folklore have surrounded Prehn and prehnite and is a relatively new material to the lapidary field. It's pleasant green color makes beautiful cabs. -WET pic.-(6. oz.)
