Chemical Formula: CaCO3

Chemical Name: Calcium Carbonate

Mineral Class: Carbonate

Mineral Notes: Calcite is one of the commonest minerals, being the main constituent of limestone. Calcite is often fluorescent, a small amount of Managnese is enough to make it glow red under UV light. The mineral will bubble in acid distinguishing it from many similar species, even other carbonates which do not dissolve so easily in cold acids.

Description: A very unusual oolitic cluster of very clean white Calcite. The specimen has a small base which shows the original point of attachment at the site of formation. The mineral has a strong luster and displays exceptionally well.

Location: Zlaté Hory, Olomouc, Moravia, Czech Republic.
