Microcline and Oligoclase Specific Gravity

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