Physical properties

Formation & geological history

Formed from cooling magma in igneous rocks such as pegmatites, where orthoclase and albite minerals intergrow and سپس separate as the rock cools, creating thin layers that scatter light.

Uses & applications

Primarily used in jewelry for cabochons, beads, and carvings. Also popular in metaphysical collections and as decorative pocket stones.

Geological facts

In ancient times, moonstones were believed to be formed from frozen rays of the moon. The peach variety is particularly prized for its warm, comforting color compared to the traditional silvery-white specimens.

Field identification & locations

Identify by its characteristic 'shiller' or internal glow when rotated under light. Often found in Sri Lanka, Madagascar, Brazil, and India. Collectors should look for uniform color and strong adularescence.
