Quartz and Erythrite Chemical Formula
While comparing Quartz and Erythrite 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 Erythrite chemical formula.
- Chemical formula of Quartz- SiO2
- Chemical formula of Erythrite- Co3(AsO4)2•8(H2O)
Quartz and Erythrite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Quartz and Erythrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Quartz and Erythrite Optical Properties during the identification of gemstone. Specific gravity of Quartz is 3.06 whereas that of Erythrite is 3.06.
