Prehnite is most often found as a vein or amygdule mineral in basaltic volcanic rock subjected to low grade burial metamorphism or hydrothermal activity.

 

Igneous Environments: Prehnite often forms in cavities or fractures within igneous rocks, particularly basaltic or volcanic rocks. These rocks are rich in silica, calcium, and aluminum, which are essential components for prehnite formation.

 

Usually ranging from pale to grass green, prehnite can also be gray, white, black, brown or colorless. Its luster is vitreous to waxy, or pearly, and its crystals are transparent to mostly translucent. Prehnite is very long-wearing and durable gemstone.
