While comparing Rutilated Quartz and Anhydrite 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 Rutilated Quartz and Anhydrite chemical formula.
Another important criteria for qualitative analysis of gemstones is Rutilated Quartz and Anhydrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rutilated Quartz and Anhydrite Optical Properties during the identification of gemstone. Specific gravity of Rutilated Quartz is 2.90-2.98 whereas that of Anhydrite is 2.90-2.98.
