While comparing Apatite and Jade 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 Apatite and Jade chemical formula.
Another important criteria for qualitative analysis of gemstones is Apatite and Jade Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Apatite and Jade Optical Properties during the identification of gemstone. Specific gravity of Apatite is 2.90-3.38 whereas that of Jade is 2.90-3.38.
