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