Rhodolite and Legrandite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Rhodolite and Legrandite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rhodolite and Legrandite Optical Properties during the identification of gemstone. Specific gravity of Rhodolite is 3.98-4.04 whereas that of Legrandite is 3.98-4.04.
