While comparing Quartz and Tremolite 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 Quartz and Tremolite chemical formula.
Another important criteria for qualitative analysis of gemstones is Quartz and Tremolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Quartz and Tremolite Optical Properties during the identification of gemstone. Specific gravity of Quartz is 2.95-3.07 whereas that of Tremolite is 2.95-3.07.
