Williamsite and Seraphinite Physical Properties

Williamsite and Seraphinite Chemical Formula

While comparing Williamsite and Seraphinite 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 Seraphinite chemical formula.

• Chemical formula of Williamsite- (Mg,Fe2+ ) 3Si 2O 5(OH) 4Anthony et al , Handbook of mineralogy (2001)
• Chemical formula of Seraphinite- (Mg,Fe2+ ) 5Al(Si 3Al)O 10(OH) 8Anthony et al , Handbook of mineralogy (2001)

Williamsite and Seraphinite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Williamsite and Seraphinite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Williamsite and Seraphinite Optical Properties during the identification of gemstone. Specific gravity of Williamsite is 2.60-3.02 whereas that of Seraphinite is 2.60-3.02.
