While comparing Hyacinth and Rhyolite physical properties, the important data you should know is its chemical composition. Since chemical formula defines the molecular structure of the crystal, most of the physical properties like color, tenacity, solubility are governed by Hyacinth and Rhyolite chemical formula.
Another important criteria for qualitative analysis of gemstones is Hyacinth and Rhyolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hyacinth and Rhyolite Optical Properties during the identification of gemstone. Specific gravity of Hyacinth is Not Available whereas that of Rhyolite is Not Available.
