While comparing Kunzite and Scheelite 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 Kunzite and Scheelite chemical formula.
Another important criteria for qualitative analysis of gemstones is Kunzite and Scheelite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Kunzite and Scheelite Optical Properties during the identification of gemstone. Specific gravity of Kunzite is 5.9-6.3 whereas that of Scheelite is 5.9-6.3.
