While comparing Oligoclase and Tourmaline Bi Color 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 Oligoclase and Tourmaline Bi Color chemical formula.
Another important criteria for qualitative analysis of gemstones is Oligoclase and Tourmaline Bi Color Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Oligoclase and Tourmaline Bi Color Optical Properties during the identification of gemstone. Specific gravity of Oligoclase is Not Available whereas that of Tourmaline Bi Color is Not Available.
