Star moonstone is a gem quality variety which exhibits a rare asterism effect under specific lighting. When viewing star moonstone, a four-rayed star will appear to float across the surface of the stone. The effect is best viewed under a direct light source and while viewing the stone from different angles. In addition to its rare asterism, star moonstone is known to exhibit adularescence, an optical trait that moonstone is particularly known for. Adularescence is best described as a milky sheen or a wavy glowing light which appears to come from below the surface.

The resulting sheen most commonly occurs in white, blue or blue-orange color and it appears with the four-rayed star.

Some rare gems may exhibit a cat's eye effect (chatoyancy) rather than asterism, and are known as cat's eye moonstone gems. Cat's eye moonstone is exceptionally rare and highly desirable.

Star Moonstone set in 925 silver. Rhodium plated.
