Strontianite and Calcite Chemical Formula
While comparing Strontianite 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 Strontianite and Calcite chemical formula.

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