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

Montebrasite and Kyanite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Montebrasite and Kyanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Montebrasite and Kyanite Optical Properties during the identification of gemstone. Specific gravity of Montebrasite is 3.53-3.65 whereas that of Kyanite is 3.53-3.65.
