Gaylussite and Nephrite Chemical Formula
While comparing Gaylussite and Nephrite 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 Gaylussite and Nephrite chemical formula.
- Chemical formula of Gaylussite- Na2Ca(CO3)2•5(H2O)
- Chemical formula of Nephrite- Ca 2(Mg,Fe) 5(OH) 2Walter Schumann , Gemstones of the world (2001) More from other references
Gaylussite and Nephrite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Gaylussite and Nephrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gaylussite and Nephrite Optical Properties during the identification of gemstone. Specific gravity of Gaylussite is 2.90-3.10 whereas that of Nephrite is 2.90-3.10.
