Prase and Vishnevite Physical Properties

Prase and Vishnevite Chemical Formula

While comparing Prase and Vishnevite 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 Prase and Vishnevite chemical formula.

Prase and Vishnevite Specific Gravity

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