Calcite, which can be found in almost any colour, occurs in more crystal formations than any other mineral.
The shape and size of calcite crystals can vary greatly.
Calcite is a soft mineral, so it must be handled carefully.
Some varieties demonstrate double refraction of light, meaning when light passes through, the crystal splits it into two rays, creating a double image.
One of the most common minerals on Earth, calcite forms many rock types. It can also be found in caves as stalagmites and stalactites.
