Physical properties
Hardness: 6-6.5 on Mohs scale. Color: Pale peach, light pinkish-beige, flesh-toned. Luster: Vitreous to pearly. Crystal Structure: Monoclinic. Cleavage: Perfect in two directions forming right angles. Specific gravity: ~2.56.
Formation & geological history
Formed in pegmatites and metamorphic rocks from slowly cooling magma containing potassium-rich feldspar mixtures. As the magma cools, orthoclase and albite separate into microscopic alternating layers, producing adularescence.
Uses & applications
Widely used in lapidary art, jewelry (beads, cabochons, pendants), pocket stones, and crystal healing/metaphysical practices.
Geological facts
Peach Moonstone is a variety of feldspar known for its soft, warm color caused by trace iron impurities within the potassium-rich aluminum silicate structure.
Field identification & locations
Identified by its smooth tumbled texture, light peach tone, and characteristic subtle pearly schiller or glow under light. Commonly mined in India, Madagascar, Sri Lanka, and Brazil.
