Moonstone Gem Prices: A Comprehensive Guide

Understanding the Factors that Determine Moonstone Gem Prices

Moonstone is a captivating gemstone known for its enchanting iridescent glow. Its value, like that of any other gemstone, is influenced by a range of factors, including carat weight, color, clarity, and cut.

Carat Weight

Carat weight, measured in carats (cts), is the most significant factor determining moonstone prices. Larger stones are generally more valuable due to their scarcity. The price per carat tends to increase exponentially as the carat weight increases.

Color

Moonstone is primarily found in white, cream, or gray colors. The most desirable varieties exhibit a strong blue or rainbow sheen, known as adularescence. The intensity and uniformity of adularescence significantly impact the gem's value.

Clarity

Moonstone is typically included with mineral inclusions or fractures. The fewer inclusions visible to the unaided eye, the higher the stone's clarity grade and value.

Cut

Moonstone can be cut into various shapes, including cabochon, oval, round, and pear. Cabochon cuts, which preserve the stone's natural glow, are commonly used for moonstone. The precision and symmetry of the cut also affect the gem's overall appeal.
