Gedrite and Calcite Chemical Formula
While comparing Gedrite and Calcite physical properties, the important data you should know is its chemical composition. Since chemical formula defines the molecular structure of the crystal, most of the physical properties like color, tenacity, solubility are governed by Gedrite and Calcite chemical formula.

Gedrite and Calcite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Gedrite and Calcite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gedrite and Calcite Optical Properties during the identification of gemstone. Specific gravity of Gedrite is 2.67-2.73 whereas that of Calcite is 2.67-2.73.
