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

Moonstone and Brucite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Moonstone and Brucite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Moonstone and Brucite Optical Properties during the identification of gemstone. Specific gravity of Moonstone is 2.39 whereas that of Brucite is 2.39.
