Humite and Selenite Specific Gravity

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