Richterite and Esperite Physical Properties

Richterite and Esperite Chemical Formula

While comparing Richterite and Esperite 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 Esperite chemical formula.

• Chemical formula of Richterite- Na(CaNa)(Mg,Fe++)5(Si8O22)(OH)2
• Chemical formula of Esperite- PbCa 3Zn 4(SiO 4) 4Anthony et al , Handbook of mineralogy (2001)

Richterite and Esperite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Richterite and Esperite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Richterite and Esperite Optical Properties during the identification of gemstone. Specific gravity of Richterite is 4.28-4.42 whereas that of Esperite is 4.28-4.42.
