Oligoclase and Pectolite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Oligoclase and Pectolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Oligoclase and Pectolite Optical Properties during the identification of gemstone. Specific gravity of Oligoclase is 2.74-2.90 whereas that of Pectolite is 2.74-2.90.
