Brucite and Carnelian Physical Properties

Brucite and Carnelian Chemical Formula

While comparing Brucite and Carnelian 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 Carnelian chemical formula.

• Chemical formula of Carnelian- SiO₂

Brucite and Carnelian Specific Gravity

Another important criteria for qualitative analysis of gemstones is Brucite and Carnelian Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Brucite and Carnelian Optical Properties during the identification of gemstone. Specific gravity of Brucite is 2.58-2.64 whereas that of Carnelian is 2.58-2.64.
