Fluorapatite and Melanite Chemical Formula
While comparing Fluorapatite and Melanite 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 Fluorapatite and Melanite chemical formula.

Fluorapatite and Melanite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Fluorapatite and Melanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Fluorapatite and Melanite Optical Properties during the identification of gemstone. Specific gravity of Fluorapatite is 3.70-4.10 whereas that of Melanite is 3.70-4.10.
