Brown Aragonite Tumbled 2cm - 2.5cm

Naturally tumbled Brown Aragonite in a 2–2.5cm size, displaying warm caramel to dark chocolate brown tones with a semi-translucent quality and visible layered banding throughout. Each piece varies in the depth of brown colouring and clarity of banding, giving every stone its own distinct character. A popular choice for crystal collections, display bowls, and earth-toned decorative styling.

Aragonite is a calcium carbonate mineral (CaCO₃) and a polymorph of calcite — meaning it shares the same chemical composition but has a different crystal structure. It forms in a variety of geological environments including marine sediments, hot spring deposits, and oxidised zones of ore deposits. The warm brown colouring in these specimens comes from iron oxide impurities within the crystal structure. Aragonite is also the primary mineral component of pearls and the inner layer of many mollusk shells.
