Prehnite and Anatase Chemical Formula
While comparing Prehnite and Anatase 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 Prehnite and Anatase chemical formula.

Prehnite and Anatase Specific Gravity
Another important criteria for qualitative analysis of gemstones is Prehnite and Anatase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Prehnite and Anatase Optical Properties during the identification of gemstone. Specific gravity of Prehnite is 3.82-3.97 whereas that of Anatase is 3.82-3.97.
