Usage
What is moonstone? Moonstone is a variety of gemstone that’s commonly milky white with a blue, silver, or multicolored iridescent tint. It is a variety of the mineral feldspar (more specifically, adularia or orthoclase). Moonstones can be transparent or semitransparent. More transparent moonstones are typically more valuable and higher in price. The moonstone is one of the birthstones for the month of June, along with pearl and alexandrite. It’s associated with the zodiac signs Gemini and Cancer. The word moonstone is also sometimes used to refer to other varieties of feldspar, or, less technically, to any milky-colored gemstone. Example: I have a moonstone ring that gives off a blue shine when it catches the light.
