What is Moonstone Garnet?

Moonstone garnet, while not a recognized mineralogical classification, generally refers to certain types of garnets that display characteristics similar to moonstone. Most commonly, this term is applied to specific varieties of grossular garnets, such as hessonite garnet, or sometimes to tsavorite or demantoid garnets that possess an unusual sheen or color play. The ‘moonstone’ effect, known as adularescence, is a rare phenomenon in garnets, making such specimens exceptionally valuable. True adularescence is typically associated with feldspar minerals like moonstone and orthoclase. When found in garnets, it’s often a result of specific inclusions or microstructures within the crystal lattice that refract light in a unique way, producing a schiller or shimmer.
