Beudantite and Lazulite Chemical Formula
While comparing Beudantite 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 Beudantite and Lazulite chemical formula.
- Chemical formula of Beudantite- PbFe+++3(AsO4)(SO4)(OH)6
- Chemical formula of Lazulite- (Mg,Fe)Al 2(PO 4) 2(OH) 2Arthur Thomas , Gemstones (2009) More from other references
Beudantite and Lazulite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Beudantite and Lazulite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Beudantite and Lazulite Optical Properties during the identification of gemstone. Specific gravity of Beudantite is 3.04-3.17 whereas that of Lazulite is 3.04-3.17.
