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

Calcite and Thulite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Calcite and Thulite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Calcite and Thulite Optical Properties during the identification of gemstone. Specific gravity of Calcite is 3.1 whereas that of Thulite is 3.1.
