Emerald and Amber Chemical Formula
While comparing Emerald and Amber 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 Emerald and Amber chemical formula.
- Chemical formula of Emerald- Be3Al2SiO6
- Chemical formula of Amber- [C,H,O]
Emerald and Amber Specific Gravity
Another important criteria for qualitative analysis of gemstones is Emerald and Amber Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Emerald and Amber Optical Properties during the identification of gemstone. Specific gravity of Emerald is 1.05-1.10 whereas that of Amber is 1.05-1.10.
