Gedrite and Sapphire Physical Properties

Gedrite and Sapphire Chemical Formula

While comparing Gedrite and Sapphire 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 Gedrite and Sapphire chemical formula.

• Chemical formula of Gedrite- (Mg,Fe2+ ) 2[(Mg,Fe2+ ) 3Al 2](Si 6Al 2)O 22(OH) 2Anthony et al , Handbook of mineralogy (2001)
• Chemical formula of Sapphire- Al ₂ O ₃

Gedrite and Sapphire Specific Gravity

Another important criteria for qualitative analysis of gemstones is Gedrite and Sapphire Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gedrite and Sapphire Optical Properties during the identification of gemstone. Specific gravity of Gedrite is 3.95-4.03 whereas that of Sapphire is 3.95-4.03.
