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

Eosphorite and Prehnite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Eosphorite and Prehnite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Eosphorite and Prehnite Optical Properties during the identification of gemstone. Specific gravity of Eosphorite is 2.80-2.95 whereas that of Prehnite is 2.80-2.95.
