4.2" Botryoidal, Red-Orange Aragonite - Chihuahua, Mexico

This is a beautiful, red-orange botryoidal aragonite formation that was collected from Chihuahua, Mexico. The layers of mineral formation can be seen when viewing what could be considered the underside of the specimen.

Aragonite is one of two common calcium carbonate (CaCO3) minerals: the other is calcite, of which aragonite forms as a pseudomorph. Its crystal lattice differs from calcite, resulting in a different crystal shape. It displays a translucent to white color when pure, and when impure can vary between yellow, green, pink, blue and brown. It typically forms in low-temperature hydrothermal veins, in hot springs, and as precipitates from chemicals in sedimentary rock. It can also form under biological processes: aragonite forms naturally in most mollusk shells, and as the calcareous endoskeleton most corals.
