Topaz and Amblygonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Topaz and Amblygonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Topaz and Amblygonite Optical Properties during the identification of gemstone. Specific gravity of Topaz is 2.98-3.10 whereas that of Amblygonite is 2.98-3.10.
