CALCITE is usually a clear or whitish stone, but calcite also occurs in a variety of shapes and colors. It is often fluorescent, and a small amount of manganese is enough to make it glow red under UV light. It has a strong double refraction — a phenomenon that occurs when a light ray enters the crystal and splits up into two separate rays, making anything observed through the crystal appear as double. The gemstone was used as an inlay on the throne in the tomb of King Tutankhamen, which dates to around 1340 B.C.
