Ametrine and Gypsum Chemical Formula
While comparing Ametrine and Gypsum 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 Ametrine and Gypsum chemical formula.

Ametrine and Gypsum Specific Gravity
Another important criteria for qualitative analysis of gemstones is Ametrine and Gypsum Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Ametrine and Gypsum Optical Properties during the identification of gemstone. Specific gravity of Ametrine is 2.20-2.40 whereas that of Gypsum is 2.20-2.40.
