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

Brucite and Omphacite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Brucite and Omphacite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Brucite and Omphacite Optical Properties during the identification of gemstone. Specific gravity of Brucite is 3.16-3.43 whereas that of Omphacite is 3.16-3.43.
