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

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