- Chemical formula of Lepidolite- Mg 3Si 4O 10(OH) 2Ulrich Henn and Claudio C.
Zircon and Lepidolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Zircon and Lepidolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Zircon and Lepidolite Optical Properties during the identification of gemstone. Specific gravity of Zircon is 2.80-2.90 whereas that of Lepidolite is 2.80-2.90.
