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

Pollucite and Fuchsite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Pollucite and Fuchsite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pollucite and Fuchsite Optical Properties during the identification of gemstone. Specific gravity of Pollucite is 2.77-2.88 whereas that of Fuchsite is 2.77-2.88.
