Brazilianite and Rhyolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Brazilianite and Rhyolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Brazilianite and Rhyolite Optical Properties during the identification of gemstone. Specific gravity of Brazilianite is Not Available whereas that of Rhyolite is Not Available.
