While comparing Albite and Zincite 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 Albite and Zincite chemical formula.
Another important criteria for qualitative analysis of gemstones is Albite and Zincite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Albite and Zincite Optical Properties during the identification of gemstone. Specific gravity of Albite is 5.50-5.90 whereas that of Zincite is 5.50-5.90.
