Citrine and Emerald Chemical Formula
While comparing Citrine 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 Citrine and Emerald chemical formula.
- Chemical formula of Citrine- SiO2
- Chemical formula of Emerald- Be3Al2SiO6
Citrine and Emerald Specific Gravity
Another important criteria for qualitative analysis of gemstones is Citrine and Emerald Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Citrine and Emerald Optical Properties during the identification of gemstone. Specific gravity of Citrine is 2.67-2.78 whereas that of Emerald is 2.67-2.78.
