Quartz and Variscite Chemical Formula
While comparing Quartz and Variscite 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 Quartz and Variscite chemical formula.
- Chemical formula of Quartz- SiO2
- Chemical formula of Variscite- AlPO4 · 2(H2O)
Quartz and Variscite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Quartz and Variscite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Quartz and Variscite Optical Properties during the identification of gemstone. Specific gravity of Quartz is 2.42-2.58 whereas that of Variscite is 2.42-2.58.
