Moonstone

Moonstone is a feldspar mineral prized for its distinctive adularescence—a soft, luminous glow that appears to float beneath the stone's surface. This optical phenomenon occurs due to light scattering between microscopic layers within the crystal structure. Typically displaying a milky white or pearlescent sheen, moonstone ranges from translucent to semi-transparent and is often cut en cabochon to maximize its visual appeal. Valued in both jewelry and mineral collections, it rates 6-6.5 on the Mohs hardness scale. Moonstone is sourced globally, with notable deposits in India, Sri Lanka, and Madagascar, each producing stones with unique color variations and intensity of the characteristic glow.
