What is Moonstone?

Moonstone is a feldspars named "adularia" or "Selenite" and is a silicate of potassium aluminium.
Like a diamond, when uncut, the moonstone can be dull in appearance. However it is when it is cut that all the light effects begin to shine through. Often a moonstone will be 'cabochon' cut with smooth round curvatures.

How does the colour change?
Inbound light rays are refracted inside the stone and distorted by the scales or layers inside the stone
Moonstone is quite fragile and is only 6 on the Mohs' scale. However a dulled Moonstone can be specially polished to enhance its mystical light.

Moonstone is said to enhance concentration and intuition.
