While comparing Nano Polycrystalline Diamond 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 Nano Polycrystalline Diamond and Fluorapatite chemical formula.
Another important criteria for qualitative analysis of gemstones is Nano Polycrystalline Diamond and Fluorapatite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Nano Polycrystalline Diamond and Fluorapatite Optical Properties during the identification of gemstone. Specific gravity of Nano Polycrystalline Diamond is 3.1-3.25 whereas that of Fluorapatite is 3.1-3.25.
