Aragonite is a calcium carbonate mineral that is a paramorph of calcite, meaning the two share a chemical composition but have different crystal structures. It is translucent or white when free of impurities, but when impurities are present, it can vary between yellow, green, pink, blue, purple, red-orange and brown. Aragonite is a collector favorite, because of the wide variety of crystal forms it takes: from colorful, globular crusts, to towering, botryoidal stalactites and branching, flos ferri trees. Aragonite is the perfect mineral for collectors who enjoy flashy colors and mysterious cave structures.
