Sinhalite and Lazulite Chemical Formula
While comparing Sinhalite and Lazulite 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 Sinhalite and Lazulite chemical formula.

Sinhalite and Lazulite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sinhalite and Lazulite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sinhalite and Lazulite Optical Properties during the identification of gemstone. Specific gravity of Sinhalite is 3.04-3.17 whereas that of Lazulite is 3.04-3.17.
