Legrandite and Prase Specific Gravity
Another important criteria for qualitative analysis of gemstones is Legrandite and Prase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Legrandite and Prase Optical Properties during the identification of gemstone. Specific gravity of Legrandite is 2.64-2.69 whereas that of Prase is 2.64-2.69.
