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

Prehnite and Periclase Specific Gravity
Another important criteria for qualitative analysis of gemstones is Prehnite and Periclase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Prehnite and Periclase Optical Properties during the identification of gemstone. Specific gravity of Prehnite is 3.7-3.9 whereas that of Periclase is 3.7-3.9.
