Moonstone

Moonstone, also known as orthoclase, is an opaque, white, semiprecious feldspar gemstone usually polished to a bluish sheen. Moonstone can be used in spells that draw inspiration from the moons or that cure or cause confusion effects. Moonstones polished with specific alchemical waxes can be attuned to one of the three moons, making them glow faintly when the moon to which the stone is attuned is up in the sky.
