Lawsonite and Beryllonite Chemical Formula
While comparing Lawsonite and Beryllonite 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 Lawsonite and Beryllonite chemical formula.

Lawsonite and Beryllonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Lawsonite and Beryllonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Lawsonite and Beryllonite Optical Properties during the identification of gemstone. Specific gravity of Lawsonite is 2.79-2.87 whereas that of Beryllonite is 2.79-2.87.
