Dioptase and Grossular Physical Properties

Dioptase and Grossular Chemical Formula

While comparing Dioptase and Grossular 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 Dioptase and Grossular chemical formula.

Dioptase and Grossular Specific Gravity

Another important criteria for qualitative analysis of gemstones is Dioptase and Grossular Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Dioptase and Grossular Optical Properties during the identification of gemstone. Specific gravity of Dioptase is 3.55-3.73 whereas that of Grossular is 3.55-3.73.
