What is the second name for moonstone?

Moon rock (adular) – belongs to the group of feldspars. The color is predominantly yellow, colorless and light gray with a bluish-gray or blue tint (iridization). In addition to iridescence in moonstones, you can find asterism, for example, in the form of a four-rayed star or the “cat’s eye” effect. The highest quality moonstone is mined in Sri Lanka [1] [2] . The main feature of moonstone is the bluish-silver shimmer that moves within the stone depending on the viewing angle. This phenomenon is called “adelarescence”, it is due to the fact that the gem consists of thin layers and plates that scatter light differently [2]. In addition to adularia, belomorite, which is a type of oligoclase with iridescence in pearl-bluish tones, is also called moonstone. Belomorite is used as an ornamental stone; it is practically not used in jewelry [1].
