Microcline and Londonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Microcline and Londonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Microcline and Londonite Optical Properties during the identification of gemstone. Specific gravity of Microcline is 3.34 whereas that of Londonite is 3.34.
