While comparing Fluorapatite and Uvite 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 Uvite chemical formula.
Another important criteria for qualitative analysis of gemstones is Fluorapatite and Uvite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Fluorapatite and Uvite Optical Properties during the identification of gemstone. Specific gravity of Fluorapatite is 2.97-3.14 whereas that of Uvite is 2.97-3.14.
