Padparadscha and Sillimanite Physical Properties

Padparadscha and Sillimanite Chemical Formula

While comparing Padparadscha and Sillimanite 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 Padparadscha and Sillimanite chemical formula.

Padparadscha and Sillimanite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Padparadscha and Sillimanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Padparadscha and Sillimanite Optical Properties during the identification of gemstone. Specific gravity of Padparadscha is 3.20-3.26 whereas that of Sillimanite is 3.20-3.26.
