While comparing Dumortierite quartz and Goshenite 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 Dumortierite quartz and Goshenite chemical formula.
Another important criteria for qualitative analysis of gemstones is Dumortierite quartz and Goshenite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Dumortierite quartz and Goshenite Optical Properties during the identification of gemstone. Specific gravity of Dumortierite quartz is 2.60-2.90 whereas that of Goshenite is 2.60-2.90.
