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

Purpurite and Hydrophane Specific Gravity
Another important criteria for qualitative analysis of gemstones is Purpurite and Hydrophane Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Purpurite and Hydrophane Optical Properties during the identification of gemstone. Specific gravity of Purpurite is 1.98-2.50 whereas that of Hydrophane is 1.98-2.50.
