Moonstone and rainbow moonstone are two of the most enchanting gemstones in the world of crystals and jewelry. Both belong to the feldspar mineral family, yet they are often mistaken for one another due to their shimmering light effects. However, their origins, optical phenomena, and cultural symbolism make them unique in their own right. If you’re choosing between moonstone vs. rainbow moonstone for your collection or jewelry, understanding their differences will help you make a confident decision.
What is Moonstone?
Moonstone is a gemstone from the feldspar group, primarily composed of orthoclase and albite. Its hallmark is adularescence - a glowing, moonlike sheen caused by light scattering between layers of minerals. This ethereal shimmer makes moonstone a favorite for spiritual jewelry, healing practices, and elegant accessories.
