Moonstone is a potassium sodium aluminum silicate mineral with chemical composition approximating KAlSi3O8. It displays a pearly or opalescent sheen, thanks to its layered internal structure of alternating orthoclase and albite crystals, which diffract light to produce the characteristic glow. This phenomenon is called adularescence or schiller, making moonstone unique among gemstones.

Formation and Sources

Moonstone forms deep within the Earth’s crust, primarily in feldspar-rich granitic and syenitic pegmatites. Major deposits are found in India, Sri Lanka, Myanmar, Australia, Madagascar, Brazil, and the United States. Sri Lanka is renowned for its transparent, blue-adularescent moonstones, while India is famous for producing fine rainbow moonstones that display a multicolor sheen.

Uses and Care

Moonstone is primarily used in rings, pendants, earrings, and bracelets due to its enchanting appearance.
