Collection: Pierre de lune

Moonstone is of the feldspar group within the orthoclase mineral family, and forms as magma loses temperature. When molten rock cools, the minerals orthoclase and albite separate into thin alternating layers. This structure forces light to scatter throughout each layer to create a billowing white to blue glow that dances across the stone's surface.

This captivating phenomena is called adularescence and the stronger and bluer the optic display, the more valuable. Moonstone is typically colorless, but can occur in a wide range of soft pastel colors. 

The gem is readily available and mined globally in Sri Lanka, India, Australia, Brazil, and elsewhere.
