Prehnite is a calcium aluminum silicate mineral that forms in the cavities of volcanic and metamorphic rocks. Major deposits exist in South Africa, Australia, Mali, and parts of the United States.
Prehnite rates 6 to 6.5 on the Mohs hardness scale, making it suitable for pendants and earrings. Rings require more care since the stone can scratch with heavy daily wear.
Prehnite ranges from pale yellow-green to deeper olive tones. The stone often appears translucent with a soft, milky glow, and some specimens contain dark epidote needle inclusions.
