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

Brucite and Purpurite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Brucite and Purpurite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Brucite and Purpurite Optical Properties during the identification of gemstone. Specific gravity of Brucite is 3.2-3.4 whereas that of Purpurite is 3.2-3.4.
