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

Gypsum and Chlorapatite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Gypsum and Chlorapatite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gypsum and Chlorapatite Optical Properties during the identification of gemstone. Specific gravity of Gypsum is 3.17-3.18 whereas that of Chlorapatite is 3.17-3.18.
