Sodalite and Montebrasite Chemical Formula
While comparing Sodalite and Montebrasite 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 Sodalite and Montebrasite chemical formula.

Sodalite and Montebrasite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sodalite and Montebrasite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sodalite and Montebrasite Optical Properties during the identification of gemstone. Specific gravity of Sodalite is 2.98-3.10 whereas that of Montebrasite is 2.98-3.10.
