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

Kyanite and Sinhalite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Kyanite and Sinhalite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Kyanite and Sinhalite Optical Properties during the identification of gemstone. Specific gravity of Kyanite is 3.46-3.50 whereas that of Sinhalite is 3.46-3.50.
