Viridine and Gahnite Chemical Formula
While comparing Viridine and Gahnite 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 Viridine and Gahnite chemical formula.

Viridine and Gahnite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Viridine and Gahnite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Viridine and Gahnite Optical Properties during the identification of gemstone. Specific gravity of Viridine is 4.00-4.62 whereas that of Gahnite is 4.00-4.62.
