Moonstone is one of those gems that photographs can't do justice. The floating blue sheen, called adularescence, has to be seen in person to be fully appreciated. Sri Lanka produces the finest blue moonstones in the world, and that's exactly where we source ours. Direct from partner mines, no middlemen. What to look for? A strong blue sheen that floats across the entire stone, with a clean, translucent body. The best specimens show an almost electric blue flash. Rainbow moonstones with multi-color play are also highly sought after. Check out our current stock below or reach out for something specific.

Submit a requestMoonstone is one of nature's most enchanting optical phenomena -- a gemstone that appears to hold captured moonlight within its translucent body. This mesmerizing effect, known as adularescence, is caused by the interplay of light between microscopic alternating layers of orthoclase and albite feldspar within the crystal. As the stone moves, a billowing, ethereal blue-white glow seems to float across its surface, evoking the luminous face of the moon on a clear night. No other gemstone produces this precise optical magic.
The finest moonstones in the world come from Sri Lanka, where they have been mined and treasured for millennia. Sri Lankan moonstone is distinguished by its transparent-to-translucent body with a vivid blue adularescence that appears to float within the stone rather than sitting on the surface. This "blue sheen" quality is the most valued characteristic in moonstone, and specimens with strong, uniform blue adularescence over a transparent body command the highest prices. Indian moonstone, while more abundant, typically displays a white or silvery sheen over a more opaque body.
The most important quality factor in moonstone is the strength, color, and uniformity of the adularescence. The finest specimens display a vivid blue sheen that covers the entire face of the stone evenly, with a transparent, colorless to very slightly milky body. Avoid stones with visible cloudiness, crackling, or uneven sheen distribution. Body color can range from colorless (most valued) through white, peach, and gray. The cabochon cut is traditional and most effective for displaying adularescence, though some contemporary cutters produce faceted moonstones for a more modern aesthetic.
Moonstone has been revered across cultures for thousands of years. In Hindu tradition, it is considered sacred and believed to be formed from solidified moonbeams. Art Nouveau jewelers of the early 20th century, particularly Rene Lalique, elevated moonstone to high-jewelry status. Today, moonstone has found a new audience among buyers who value its organic, mystical beauty and its connection to natural phenomena. It is the birthstone for June and is associated with intuition, balance, and new beginnings.
