Aragonite

About Aragonite

Aragonite is a calcium carbonate polymorph distinct from calcite, distinguished by its orthorhombic crystal system and unique needle-like or tabular crystal forms. This mineral is essential for collectors interested in polymorphism—the phenomenon where identical chemical compositions create different crystal structures and physical properties. Aragonite specimens exhibit delicate white, colorless, or pale yellow crystals with excellent transparency and brilliant luster.Significant aragonite deposits occur in Spain, Germany, Mexico, and Japan, with notable specimens also found in Austria and the United States. This mineral forms in marine environments, hot springs, and hydrothermal systems where specific pH and temperature conditions favor its crystallization over calcite. Pseudohexagonal twin formations are common in aragonite, creating distinctive aesthetic specimens.Explore our aragonite mineral collection to study this fascinating calcium carbonate polymorph.
