Montebrasite and Diaspore Chemical Formula

While comparing Montebrasite and Diaspore 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 Diaspore chemical formula.

Montebrasite and Diaspore Specific Gravity

Another important criteria for qualitative analysis of gemstones is Montebrasite and Diaspore Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Montebrasite and Diaspore Optical Properties during the identification of gemstone. Specific gravity of Montebrasite is 3.30-3.40 whereas that of Diaspore is 3.30-3.40.
