Jade and Humite Chemical Formula
While comparing Jade and Humite 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 Jade and Humite chemical formula.
- Chemical formula of Jade- Nephrite: Ca2(Mg,Fe)5Si8O22(OH)2 Jadeite: NaAlSi2O6
- Chemical formula of Humite- (Mg,Fe2+ ) 7(SiO 4) 3(F,OH) 2Anthony et al , Handbook of mineralogy (2001)
Jade and Humite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Jade and Humite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Jade and Humite Optical Properties during the identification of gemstone. Specific gravity of Jade is 3.20-3.32 whereas that of Humite is 3.20-3.32.
