Rhodizite and Obsidian Specific Gravity
Another important criteria for qualitative analysis of gemstones is Rhodizite and Obsidian Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rhodizite and Obsidian Optical Properties during the identification of gemstone. Specific gravity of Rhodizite is 2.35-2.60 whereas that of Obsidian is 2.35-2.60.
