Humite and Amethyst Specific Gravity
Another important criteria for qualitative analysis of gemstones is Humite and Amethyst Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Humite and Amethyst Optical Properties during the identification of gemstone. Specific gravity of Humite is 2.65 whereas that of Amethyst is 2.65.
