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