What is Blue Calcite?

Blue calcite is the pale sky-blue form of calcite (calcium carbonate). The blue colour is thought to come from traces of other elements and defects in the crystal. Most blue calcite on the market is massive (non-crystal) material from Mexico, polished into palm stones, spheres and tumbled stones.

Like all calcite, it is soft (3 on the Mohs scale) and reacts with acids.
