- Chemical formula of Jadeite- NaAlSi 2O 6Ulrich Henn and Claudio C.
Prehnite and Jadeite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Prehnite and Jadeite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Prehnite and Jadeite Optical Properties during the identification of gemstone. Specific gravity of Prehnite is 3.28-3.38 whereas that of Jadeite is 3.28-3.38.
