Zircon and Linarite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Zircon and Linarite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Zircon and Linarite Optical Properties during the identification of gemstone. Specific gravity of Zircon is 5.35 whereas that of Linarite is 5.35.
