Moonstones have a magical flash inside them, also called adularescence. These rainbow flashes are hidden inside the stone and appear when the light catches them in the right place.

Whenever I work with moonstones, I imagine a person thousands of years ago finding a moonstone on the ground and being amazed by the rainbow flash and knowing it's precious. It's hard not to believe in something bigger then you when staring into the flash of a moonstone.
