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

Sapphire and Pollucite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Sapphire and Pollucite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sapphire and Pollucite Optical Properties during the identification of gemstone. Specific gravity of Sapphire is 2.86-2.94 whereas that of Pollucite is 2.86-2.94.
