Iceland spar Wikipedia
Iceland spar, formerly called Iceland crystal and also called optical calcite, is a transparent variety of calcite, or crystallized calcium carbonate, originally brought from Iceland, and used in demonstrating the polarization of light (see polarimetry). It occurs in large readily cleavable crystals, is easily divisible into parallelepipeds, and is remarkable for its birefringence. This means that the refractive index of t

Calcite may be found in caves as stalactites or stalagmites. Calcite and aragonite are polymorphs as they have the same chemical composition (CaCO3) but have different crystal structures.
