Moonstone

Carat weight plays a meaningful role, particularly for fine blue-sheen moonstones. Larger, high-domed cabochons that show a centered, vivid sheen are notably more valuable than small or weakly adularescent stones. Commercial material is common in smaller sizes, while larger fine pieces are scarcer.

Color and sheen are primary value drivers. The most prized material features a nearly colorless to very light body color with a strong, electric blue adularescent sheen, sharply centered and mobile with light. Stones with white or diffuse sheen, or with heavily tinted body colors, are generally less valuable, though peach and rainbow varieties have their own markets.

Moonstone is usually translucent; fine stones have relatively clean interiors with only minor internal fractures that do not disturb the sheen. Large cracks, cloudiness or heavy inclusions disrupt adularescence and significantly lower value.

Cut is critical. Moonstone is almost always cut as cabochons, with dome shape and orientation carefully chosen to position the sheen centrally and perpendicular to the base. A smooth, even polish is essential for a pleasing glow. Poor orientation can result in weak or off-center adularescence.

Moonstone deposits are found in Sri Lanka, India, Myanmar, Madagascar and several other countries. Commercial supplies of standard-quality material are fairly abundant, though fine blue-sheen stones with good transparency and size are significantly less common.

Demand is strong across mass-market, artisan and fine jewelry segments, driven by moonstone's romantic associations and optical effect. Rainbow and peach moonstones are popular in contemporary boho and designer styles, while classic blue-sheen material remains a staple in fine jewelry.
