Demantoid and Gedrite Physical Properties

Demantoid and Gedrite Chemical Formula

While comparing Demantoid 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 Demantoid and Gedrite chemical formula.

• Chemical formula of Demantoid- Ca 3Fe 2(SiO 4) 3Ulrich Henn and Claudio C.
• Chemical formula of Gedrite- (Mg,Fe2+ ) 2[(Mg,Fe2+ ) 3Al 2](Si 6Al 2)O 22(OH) 2Anthony et al , Handbook of mineralogy (2001)

Demantoid and Gedrite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Demantoid and Gedrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Demantoid and Gedrite Optical Properties during the identification of gemstone. Specific gravity of Demantoid is 3.15-3.259 whereas that of Gedrite is 3.15-3.259.
