Spodumene and Faustite Chemical Formula
While comparing Spodumene and Faustite 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 Spodumene and Faustite chemical formula.
- Chemical formula of Spodumene- LiAlSi2O6
- Chemical formula of Faustite- (Zn,Cu)Al 6(PO 4) 4(OH) 8 · 4H 2OMichael OâDonoghue , Gems, Sixth Edition (2006)
Spodumene and Faustite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Spodumene and Faustite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Spodumene and Faustite Optical Properties during the identification of gemstone. Specific gravity of Spodumene is 2.9 whereas that of Faustite is 2.9.
