Labradorite
Labradorite is a gray to dark bluish feldspar mineral famous for its striking iridescent optical effect known as labradorescence, displaying flashes of blue, green, gold, and sometimes violet. It belongs to the plagioclase feldspar group and is commonly found in igneous rocks such as basalt and gabbro, as well as in metamorphic rocks. Spiritually, it is often associated with protection, magic, and enhancing psychic abilities. Chemically, its formula is (Ca,Na)(Al,Si)₄O₈.
