About Prehnite

Prehnite is a translucent to transparent gem-quality hydrated calcium aluminium silicate. It was the first mineral to be named after an individual, and it was also the first mineral to be described from South Africa, long before South Africa became one of the most important sources for rough stones in gem quality. It was first described in 1788 after it was discovered in the Karoo dolerites of Cradock, South Africa. Prehnite was later named after its discoverer, Colonel Hendrik von Prehn (1733-1785), a Dutch mineralogist and an early governor of the Cape of Good Hope colony.

Facts:

  • Mohs Hardness: 6 to 6.5
  • Aggregate
  • Calcium-Aluminium-Silicate
