Moonstone

Moonstone is a variety of feldspar. It is recognized by the play of light or shimmer which always looks different upon moving the stone.
The shimmer of Moonstone is caused by refracted light rays in the stone.
Many cultures have attached myths and much spiritual importance to this stone.The underlying subject for Moonstone throughout history is its connection to the moon, fertility, femininity and the Goddess.
One of my favourite stories about this crystal is that the Romans thought that Moonstone was magically created out of the rays of moonlight.
