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

Periclase and Fluorapatite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Periclase and Fluorapatite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Periclase and Fluorapatite Optical Properties during the identification of gemstone. Specific gravity of Periclase is 3.1-3.25 whereas that of Fluorapatite is 3.1-3.25.
