Quartz and Williamsite Physical Properties

Quartz and Williamsite Chemical Formula

While comparing Quartz and Williamsite 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 Williamsite chemical formula.

• Chemical formula of Quartz- SiO₂
• Chemical formula of Williamsite- (Mg,Fe2+ ) 3Si 2O 5(OH) 4Anthony et al , Handbook of mineralogy (2001)

Quartz and Williamsite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Quartz and Williamsite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Quartz and Williamsite Optical Properties during the identification of gemstone. Specific gravity of Quartz is 2.51-2.63 whereas that of Williamsite is 2.51-2.63.
