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