Aragonite Crystals Ankylosaurus Our research team has discoveredNOTE THAT YOU WILL RECEIVE A SPECIMEN OF EQUAL OR BETTER QUALITY THAN THE ONE SHOWN Aragonite is a carbonate mineral, one of the two common, naturally occurring polymorphs of calcium carbonate, CaCO3.

Repeated twinning results in pseudo hexagonal forms. Aragonite
