Nephrite and Tektite Physical Properties

Nephrite and Tektite Chemical Formula

While comparing Nephrite and Tektite 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 Nephrite and Tektite chemical formula.

• Chemical formula of Nephrite- Ca 2(Mg,Fe) 5(OH) 2Walter Schumann , Gemstones of the world (2001) More from other references
• Chemical formula of Tektite- SiO2, Al2O3, FeO, MgO, CaO, K2O, Na2O

Nephrite and Tektite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Nephrite and Tektite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Nephrite and Tektite Optical Properties during the identification of gemstone. Specific gravity of Nephrite is 2.34-2.51 whereas that of Tektite is 2.34-2.51.
