Edenite and Elbaite Chemical Formula
While comparing Edenite and Elbaite 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 Edenite and Elbaite chemical formula.
- Chemical formula of Edenite- NaCa2Mg5Si7AlO22(OH)2
- Chemical formula of Elbaite- Na(Li 1.5Al 1.5)Al 6(Si 6O 18)(BO 3) 3(OH) 3(OH)Gemdat.org , Management Team (2012) More from other references
Edenite and Elbaite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Edenite and Elbaite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Edenite and Elbaite Optical Properties during the identification of gemstone. Specific gravity of Edenite is 2.90-3.10 whereas that of Elbaite is 2.90-3.10.
