Prehnite
The Gentle Healer of Healers
Also known as: Cape Emerald, Cape Chrysolite
About the stone

Prehnite is a translucent calcium-aluminum silicate mineral, usually pale green to yellow-green, often forming rounded, grape-like clusters. Colonel Hendrik von Prehn collected early specimens in South Africa in the 1770s, and Abraham Gottlob Werner described and named it in his honor in 1788; it is widely credited as the first mineral named after a person. Notable sources include South Africa, Mali, Namibia, Australia, India, and the United States, particularly New Jersey. Historical trade names include “Cape Emerald” and “Cape Chrysolite,” although it is neither emerald nor peridot. In modern crystal lore, prehnite is associated with intuition, dream interpretation, and spiritual growth.

Care and handling
Prehnite has a hardness of 6 to 6.5 and good cleavage, so it should be protected from hard knocks and from harder stones that can scratch it. Clean it with a soft damp cloth and mild soapy water, then dry it gently. Avoid ultrasonic cleaners, steamers, harsh chemicals, and high heat. Wearing it in rings or bracelets exposes it to impact, so remove it during rough activity.
Individual experiences with Prehnite vary, and its gentle effects are subtle and personal. Use it mindfully and with kindness toward yourself, especially if you spend your days caring for others.
