Williamsite and Jade Chemical Formula
While comparing Williamsite and Jade 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 Williamsite and Jade chemical formula.
- Chemical formula of Williamsite- (Mg,Fe2+ ) 3Si 2O 5(OH) 4Anthony et al , Handbook of mineralogy (2001)

Williamsite and Jade Specific Gravity
Another important criteria for qualitative analysis of gemstones is Williamsite and Jade Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Williamsite and Jade Optical Properties during the identification of gemstone. Specific gravity of Williamsite is 2.90-3.38 whereas that of Jade is 2.90-3.38.
