Starlite and Langbeinite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Starlite and Langbeinite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Starlite and Langbeinite Optical Properties during the identification of gemstone. Specific gravity of Starlite is Not Available whereas that of Langbeinite is Not Available.
