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

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