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