Iceland stone, with a chemical composition of CaCO3, is a colorless, transparent, and pure calcite. Due to its special physical properties, it is called a special non-metallic mineral. It was first discovered in Iceland, hence it is called "Iceland Stone". It has the highest birefringence and polarization performance in white transparent crystal minerals. The crystals of high-quality ice spar are produced in the calcite veins of basalt and zeolite calcite veins.
