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

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