Spodumene and Jade Chemical Formula
While comparing Spodumene and Jade 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 Jade chemical formula.
- Chemical formula of Spodumene- LiAlSi2O6
- Chemical formula of Jade- Nephrite: Ca2(Mg,Fe)5Si8O22(OH)2 Jadeite: NaAlSi2O6
Spodumene and Jade Specific Gravity
Another important criteria for qualitative analysis of gemstones is Spodumene and Jade Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Spodumene and Jade Optical Properties during the identification of gemstone. Specific gravity of Spodumene is 2.90-3.38 whereas that of Jade is 2.90-3.38.
