Alexandrite and Narsarsukite Chemical Formula
While comparing Alexandrite and Narsarsukite 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 Alexandrite and Narsarsukite chemical formula.
- Chemical formula of Alexandrite- BeAl 2 O 4
- Chemical formula of Narsarsukite- Na 2(Ti,Fe)Si 4(O,F) 11Ulrich Henn and Claudio C.
Alexandrite and Narsarsukite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Alexandrite and Narsarsukite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Alexandrite and Narsarsukite Optical Properties during the identification of gemstone. Specific gravity of Alexandrite is 2.72-2.83 whereas that of Narsarsukite is 2.72-2.83.
