Fluorite and Gedrite Chemical Formula
While comparing Fluorite and Gedrite 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 Fluorite and Gedrite chemical formula.
- Chemical formula of Fluorite- CaF2
- Chemical formula of Gedrite- (Mg,Fe2+ ) 2[(Mg,Fe2+ ) 3Al 2](Si 6Al 2)O 22(OH) 2Anthony et al , Handbook of mineralogy (2001)
Fluorite and Gedrite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Fluorite and Gedrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Fluorite and Gedrite Optical Properties during the identification of gemstone. Specific gravity of Fluorite is 3.15-3.259 whereas that of Gedrite is 3.15-3.259.
