Pollucite and Brucite Physical Properties

Pollucite and Brucite Chemical Formula

While comparing Pollucite 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 Pollucite and Brucite chemical formula.

Pollucite and Brucite Specific Gravity

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