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

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