- Chemical formula of Moldavite- SiO 2(+Al 2O 3)Walter Schumann , Gemstones of the world (2001)
Spodumene and Moldavite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Spodumene and Moldavite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Spodumene and Moldavite Optical Properties during the identification of gemstone. Specific gravity of Spodumene is 2.32-2.38 whereas that of Moldavite is 2.32-2.38.
