Natural Moonstone

Moonstone is the most well known variety of orthoclase feldspar. It characteristically exhibits a milky floating blue light known as adularescence or the schiller effect. This lovely sheen is due to a combination of orthoclase and albite arranged in layers. Light reflected from the layers if they are not too thick is responsible for the unusual optical properties.

Moonstone is usually fashioned en cabochon with the blue colors commanding higher prices.

A new kind of moonstone has also been recently discovered in Tanzania. Potassium-feldspar (K-feldspar) alcali feldspar, or moonstone with weak asterism, the stones exhibit cat's eyes with a weaker ray perpendicular to the eye producing a four ray star in some specimens. We call it "sunstar".
