Carnallite and Nephrite Chemical Formula
While comparing Carnallite 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 Carnallite and Nephrite chemical formula.
- Chemical formula of Carnallite- KMgCl3•6(H2O)
- Chemical formula of Nephrite- Ca 2(Mg,Fe) 5(OH) 2Walter Schumann , Gemstones of the world (2001) More from other references
Carnallite and Nephrite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Carnallite and Nephrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Carnallite and Nephrite Optical Properties during the identification of gemstone. Specific gravity of Carnallite is 2.90-3.10 whereas that of Nephrite is 2.90-3.10.
