Williamsite and Datolite Chemical Formula
While comparing Williamsite and Datolite 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 Datolite chemical formula.

Williamsite and Datolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Williamsite and Datolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Williamsite and Datolite Optical Properties during the identification of gemstone. Specific gravity of Williamsite is 2.90-3.00 whereas that of Datolite is 2.90-3.00.
