Hyalite and Milarite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Hyalite and Milarite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hyalite and Milarite Optical Properties during the identification of gemstone. Specific gravity of Hyalite is 2.52-2.60 whereas that of Milarite is 2.52-2.60.
