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

Chlorapatite and Gypsum Specific Gravity
Another important criteria for qualitative analysis of gemstones is Chlorapatite and Gypsum Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chlorapatite and Gypsum Optical Properties during the identification of gemstone. Specific gravity of Chlorapatite is 2.20-2.40 whereas that of Gypsum is 2.20-2.40.
