Moss Agate and Sapphire Specific Gravity
Another important criteria for qualitative analysis of gemstones is Moss Agate and Sapphire Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Moss Agate and Sapphire Optical Properties during the identification of gemstone. Specific gravity of Moss Agate is 3.95-4.03 whereas that of Sapphire is 3.95-4.03.
