- Chemical formula of Rhodolite- (Mg,Fe)3Al2Si3O12
Almandine and Rhodolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Almandine and Rhodolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Almandine and Rhodolite Optical Properties during the identification of gemstone. Specific gravity of Almandine is 3.84 whereas that of Rhodolite is 3.84.
