Characteristics of the Stone The name comes from the blue or white sheen, reminiscent of moonlight, obtained by cabochon-cutting transparent feldspars. Those with a blue schiller effect are specifically called "blue moonstone." Originally, pale blue moonstones rarely found in Sri Lanka were called blue moonstone, but later, feldspars produced in India and other places also came to be called blue moonstone. Therefore, particularly beautiful moonstones with a blue schiller effect from Sri Lanka are called "Royal Blue Moonstone," and those produced in the Adular Mountains of Austria, which are highly transparent and emit a beautiful blue light, are called "Adularescent Moonstone."
