Amblygonite and Purpurite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Amblygonite and Purpurite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Amblygonite and Purpurite Optical Properties during the identification of gemstone. Specific gravity of Amblygonite is 3.2-3.4 whereas that of Purpurite is 3.2-3.4.
