- Chemical formula of Mellite- Al 2(Cl 2O 12) · 18H 2OUlrich Henn and Claudio C.
Glaucophane and Mellite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Glaucophane and Mellite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Glaucophane and Mellite Optical Properties during the identification of gemstone. Specific gravity of Glaucophane is 1.58-1.60 whereas that of Mellite is 1.58-1.60.
