Calcite HyperPhysics Concepts

The center sample above is manganoan calcite from Idarado Mine, Ouray, Colorado. Sample size 1518 cm. The right sample is calcite with duftite inclusions from Tsumeb, Namibia. Sample size about 12 cm. Calcite, CaCO 3, is the most abundant of the carbonate minerals. Clear calcite has many optical appliions because of its large birefringence.

Iceland spar Wikipedia

Iceland spar, formerly known as Iceland crystal (Icelandic: silfurberg lit. silverrock), 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 rhombuses, and is remarkable for its birefringence.
