Forsterite and Taaffeite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Forsterite and Taaffeite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Forsterite and Taaffeite Optical Properties during the identification of gemstone. Specific gravity of Forsterite is 3.60-3.61 whereas that of Taaffeite is 3.60-3.61.
