Iceland spar is a clear variation of calcite, it exhibits the rhombic crystal system of calcite perfectly, the crystals easily divide into rhombs, making them well sought after for a variety of reasons.

When light passes through one of the crystals, it is divided into two rays at different angles which results in a double refraction effect.
