Moonstone, like labradorite, is a type of feldspar. Rainbow or blue moonstone is white/transparent with a brilliant, colorful flash of color!
The flash of blue color is caused by the interuption of light beams at various mineral layers. It's called blue adularescence.
Basically, as the feldspar is forming, various types of feldspar cool at different rates, creating layers. These different layers interact/interupt light passing through and scatter it, causing the flash! (Remember, white light is the amalgamation of all visible colors. In the case of this moonstone, only the blue light, which has a smaller wavelength, is able to escape the layers!)
Moonstone is the perfect romantic gift, as even lovers in ancient Rome exchanged this stone. Moonstone jewelry became fashionable again in the Art Nouveau period.
