Demantoid and Lazulite Physical Properties

Demantoid and Lazulite Chemical Formula

While comparing Demantoid and Lazulite 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 Lazulite chemical formula.

• Chemical formula of Demantoid- Ca 3Fe 2(SiO 4) 3Ulrich Henn and Claudio C.
• Chemical formula of Lazulite- (Mg,Fe)Al 2(PO 4) 2(OH) 2Arthur Thomas , Gemstones (2009) More from other references

Demantoid and Lazulite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Demantoid and Lazulite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Demantoid and Lazulite Optical Properties during the identification of gemstone. Specific gravity of Demantoid is 3.04-3.17 whereas that of Lazulite is 3.04-3.17.
