Richterite and Nephrite Physical Properties

Richterite and Nephrite Chemical Formula

While comparing Richterite 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 Richterite and Nephrite chemical formula.

• Chemical formula of Richterite- Na(CaNa)(Mg,Fe++)5(Si8O22)(OH)2
• Chemical formula of Nephrite- Ca 2(Mg,Fe) 5(OH) 2Walter Schumann , Gemstones of the world (2001) More from other references

Richterite and Nephrite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Richterite and Nephrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Richterite and Nephrite Optical Properties during the identification of gemstone. Specific gravity of Richterite is 2.90-3.10 whereas that of Nephrite is 2.90-3.10.
