While comparing Turquoise and Chromite 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 Turquoise and Chromite chemical formula.
Another important criteria for qualitative analysis of gemstones is Turquoise and Chromite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Turquoise and Chromite Optical Properties during the identification of gemstone. Specific gravity of Turquoise is 4.5-4.8 whereas that of Chromite is 4.5-4.8.
