Calcite, which gets its name from 34chalix34 the Greek word for lime, is a most amazing and yet, most common is one of the most common minerals on the face of the Earth, comprising about 4 by weight of the Earth39s crust and is formed in many different geological environments.
Calcite is truly one of the best collection type minerals. There are lots of interesting forms and varieties as well as colorful and beautiful specimens to collect. It is generally easy to identify using its rhobohedral cleavage, reaction to acid and double refraction and makes for a great classroom example of these properties.

Calcite belongs to the calcite group of minerals, a group of related carbonates that are isomorphous with one another. They are similar in many physical properties, and may partially or fully replace one another, forming a solid solution members of the calcite group crystallize in the trigonal system, have perfect rhombohedral cleavage, and exhibit strong double refraction in
The gold is perched on and in white calcite. From the collection of Dr. Alan Barnes of the UK, with label. I purchased this at the Munich show and the belief was from those who know more than I, that it came from the Roata Mine in Cavnic, though I cannot say the mine attribution with 100 percent certainty.
