Labradorite and Nifontovite Chemical Formula
While comparing Labradorite and Nifontovite 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 Labradorite and Nifontovite chemical formula.
- Chemical formula of Labradorite- (Na,Ca)1-2Si3-2O8
- Chemical formula of Nifontovite- Ca 3B 6O 6(OH) 12 · 2H 2OAnthony et al , Handbook of Mineralogy (2001)
Labradorite and Nifontovite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Labradorite and Nifontovite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Labradorite and Nifontovite Optical Properties during the identification of gemstone. Specific gravity of Labradorite is 2.35-2.36 whereas that of Nifontovite is 2.35-2.36.
