While comparing Milky quartz and Simpsonite 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 Milky quartz and Simpsonite chemical formula.
Another important criteria for qualitative analysis of gemstones is Milky quartz and Simpsonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Milky quartz and Simpsonite Optical Properties during the identification of gemstone. Specific gravity of Milky quartz is Not Available whereas that of Simpsonite is Not Available.
