Calcite, which gets its name from “chalix” the Greek word for lime, is a most amazing and yet, most common mineral.  It is one of the most common minerals on the face of the Earth, comprising about 4% by weight of the Earth’s crust and is formed in many different geological environments.  Calcite can form rocks of considerable mass and constitutes a significant part of all three major rock classification types.

Calcite is even a major component in the igneous rock called carbonatite and forms the major portion of many hydrothermal veins.  Some of these rock types are composed of better than 99% calcite.  Why would a collector be interested in such a common mineral? Its extraordinary diversity and beauty!

With calcite so abundant and so widely distributed it is no wonder that it can be so varied.  The crystals of calcite can form literally a thousand different shapes.  By combining the basic forms of the positive rhombohedron, negative rhombohedron, steeply, moderately and slightly inclined rhombohedrons, various scalahedrons, prism and pinacoid to name a few of the more common forms.  There are more than 300 crystal forms identified in calcite and these forms can combine to produce the thousand different crystal variations.  Calcite also produces many twin varieties that are favorites among twin collectors.  There are also phantoms, included crystals, color varieties, pseudomorphs and unique associations.  There simply is no end to the varieties of calcite.
