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

Chlorapatite and Augelite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Chlorapatite and Augelite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chlorapatite and Augelite Optical Properties during the identification of gemstone. Specific gravity of Chlorapatite is 2.70-2.75 whereas that of Augelite is 2.70-2.75.
