Calcite

Calcite is number 3 on the Mohs hardness scale; thus it can be scratched readily by a knife blade or geologic pick It has a specific gravity of Three perfect cleavages give calcite its six sided polyhedrons with diamond shaped faces; the angles defining the faces are 78° and 102° The three important crystal habits distinctive shapes of the mineral of calcite are 1 prismatic
