Rutile and Atacamite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Rutile and Atacamite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rutile and Atacamite Optical Properties during the identification of gemstone. Specific gravity of Rutile is 3.745-3.776 whereas that of Atacamite is 3.745-3.776.
