Williamsite and Emerald Physical Properties

Williamsite and Emerald Chemical Formula

While comparing Williamsite and Emerald 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 Emerald chemical formula.

• Chemical formula of Williamsite- (Mg,Fe2+ ) 3Si 2O 5(OH) 4Anthony et al , Handbook of mineralogy (2001)
• Chemical formula of Emerald- Be₃Al₂SiO₆

Williamsite and Emerald Specific Gravity

Another important criteria for qualitative analysis of gemstones is Williamsite and Emerald Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Williamsite and Emerald Optical Properties during the identification of gemstone. Specific gravity of Williamsite is 2.67-2.78 whereas that of Emerald is 2.67-2.78.
