Chrysoprase and Gedrite Physical Properties

Chrysoprase and Gedrite Chemical Formula

While comparing Chrysoprase 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 Chrysoprase and Gedrite chemical formula.

• Chemical formula of Chrysoprase- SiO₂ (with a high level of nickel impurities )
• Chemical formula of Gedrite- (Mg,Fe2+ ) 2[(Mg,Fe2+ ) 3Al 2](Si 6Al 2)O 22(OH) 2Anthony et al , Handbook of mineralogy (2001)

Chrysoprase and Gedrite Specific Gravity

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