Aragonite
Aragonite is a mineral that is commonly found in sedimentary rocks such as limestone, dolomite, and marble. It is a polymorph of calcium carbonate, which means that it has the same chemical formula as calcite but a different crystal structure. Aragonite is named after the Aragon region in Spain where it was first discovered.

A very impressive big cabinet sized display specimen of Aragonite from Morro Bay, San Luis Obispo County, California. The piece was actually somewhat famous going back to the early 1970s, as it was a multi-award-winning specimen at several California mineral shows when it was part of the collection of Edwin D. Allabough.

Aragonite Mineral
The mineral Aragonite is usually found in pearls. It is polymorphous with calcite, vaterite and potentially reverses it to calcite in normal conditions over time (the same chemical formula but different crystal structures).

Calcite (and Aragonite) | Common Minerals
Aragonite is a polymorph of calcite, a mineral that has the same chemical composition as calcite, but has a slightly different crystal structure. For most purposes aragonite and calcite can be considered to be the same mineral. In its crystal form, aragonite tends to have needlelike crystals and lacks calcite's rhombohedral cleavage.

Aragonite: The mineral aragonite information and pictures
Calcium carbonate forms as both Aragonite and Calcite, and these two minerals only differ in their crystallization.Calcite, the more common mineral, forms in trigonal crystals, whereas Aragonite forms orthorhombic crystals. On occasion, crystals of Aragonite and Calcite are too small to be individually determined, and it is only possible to distinguish these two minerals with optical or …

Aragonite is a mineral that belongs to the carbonate mineral group, and it is a polymorph of calcium carbonate (CaCO3). In other words, aragonite shares the same chemical composition as other common minerals like calcite and vaterite, which are all composed of calcium, carbon, and oxygen atoms in varying arrangements. The chemical formula for …
