Adamite and Grossular Chemical Formula
While comparing Adamite 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 Adamite and Grossular chemical formula.

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