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

Adamite and Jade Specific Gravity
Another important criteria for qualitative analysis of gemstones is Adamite and Jade Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Adamite and Jade Optical Properties during the identification of gemstone. Specific gravity of Adamite is 2.90-3.38 whereas that of Jade is 2.90-3.38.
