Rhodizite and Emerald Chemical Formula
While comparing Rhodizite and Emerald 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 Rhodizite and Emerald chemical formula.

Rhodizite and Emerald Specific Gravity
Another important criteria for qualitative analysis of gemstones is Rhodizite and Emerald Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rhodizite and Emerald Optical Properties during the identification of gemstone. Specific gravity of Rhodizite is 2.67-2.78 whereas that of Emerald is 2.67-2.78.
