Verdite and Londonite Chemical Formula
While comparing Verdite and Londonite 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 Verdite and Londonite chemical formula.
- Chemical formula of Verdite- NaFeS2•2(H2O)
- Chemical formula of Londonite- (Cs,K,Rb)Al 4Be 4(B,Be) 12O 28Anthony et al , Handbook of mineralogy (2001)
Verdite and Londonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Verdite and Londonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Verdite and Londonite Optical Properties during the identification of gemstone. Specific gravity of Verdite is 3.34 whereas that of Londonite is 3.34.
