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

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