Prehnite is a soft, translucent mineral belonging to the phyllosilicate group, with a chemical formula of Ca2Al(AlSi3O10)(OH)2. It typically forms in cavities within volcanic rocks, often appearing as botryoidal masses or rounded nodules, with colors ranging from pale green and yellow to gray or colorless. Known for its pearly luster and delicate, almost opalescent sheen, prehnite is prized in jewelry and mineral collections. It has a Mohs hardness of 6 to 6.5 and is commonly associated with zeolite minerals. Found in volcanic regions such as South Africa, the U.S., and Australia, prehnite is often linked to emotional healing and spiritual growth. Metaphysically, it is believed to enhance unconditional love, promote peace, and support spiritual insight and personal transformation.
