Milarite and Diaspore Chemical Formula
While comparing Milarite 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 Milarite and Diaspore chemical formula.

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