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

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