Shigaite and Danburite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Shigaite and Danburite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Shigaite and Danburite Optical Properties during the identification of gemstone. Specific gravity of Shigaite is 2.97-3.03 whereas that of Danburite is 2.97-3.03.
