Dendritic Aragonite
Dendritic Aragonite also called Cave Calcite - Aragonite is a polymorph of calcite. These means the two minerals have the same chemical composition, calcium carbonate, CaCO3, but crystallize in different systems.
Calcite crystallizes in the hexagonal system, while aragonite crystallizes in the orthorhombic system. The dendritic formations are very interesting due to the shape and high interest for collectors as well for decor proposes.
This specimen come from Sefrou – Atlas, Morocco and it's mounted in a black lacquered wood base.
