Amblygonite and Gahnite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Amblygonite and Gahnite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Amblygonite and Gahnite Optical Properties during the identification of gemstone. Specific gravity of Amblygonite is 4.00-4.62 whereas that of Gahnite is 4.00-4.62.
