Gypsum and Emerald Chemical Formula

While comparing Gypsum 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 Gypsum and Emerald chemical formula.

  • Chemical formula of Emerald- Be3Al2SiO6

Gypsum and Emerald Specific Gravity

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