Prehnite

Prehnite is a calcium aluminum silicate mineral, recognized by its pale green, sometimes yellowish or white hue, with a vitreous or pearly luster. It forms in cavities of volcanic rocks and is primarily found in South Africa, Australia, and China. Historically discovered in the 18th century, it was named after Dutch Colonel Hendrik von Prehn, who brought it to Europe. Shamans and healers have used it for its connection to the emotional and spiritual realms.
