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