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

Chlorapatite and Childrenite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Chlorapatite and Childrenite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chlorapatite and Childrenite Optical Properties during the identification of gemstone. Specific gravity of Chlorapatite is 3.06-3.25 whereas that of Childrenite is 3.06-3.25.
