Esperite and Fluorite Chemical Formula
While comparing Esperite and Fluorite 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 Esperite and Fluorite chemical formula.

Esperite and Fluorite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Esperite and Fluorite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Esperite and Fluorite Optical Properties during the identification of gemstone. Specific gravity of Esperite is 3.00-3.25 whereas that of Fluorite is 3.00-3.25.
