Shigaite and Brucite Physical Properties

Shigaite and Brucite Chemical Formula

While comparing Shigaite 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 Shigaite and Brucite chemical formula.

• Chemical formula of Brucite- Mg(OH) 2Michael O’Donoghue , Gems, Sixth Edition (2006)

Shigaite and Brucite Specific Gravity

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