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

Diaspore and Moonstone Specific Gravity
Another important criteria for qualitative analysis of gemstones is Diaspore and Moonstone Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Diaspore and Moonstone Optical Properties during the identification of gemstone. Specific gravity of Diaspore is 2.56-2.60 whereas that of Moonstone is 2.56-2.60.
