Jet and Sard Physical Properties

Jet and Sard Chemical Formula

While comparing Jet and Sard 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 Jet and Sard chemical formula.

• Chemical formula of Sard- SiO 2Ulrich Henn and Claudio C.

Jet and Sard Specific Gravity

Another important criteria for qualitative analysis of gemstones is Jet and Sard Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Jet and Sard Optical Properties during the identification of gemstone. Specific gravity of Jet is 2.58-2.63 whereas that of Sard is 2.58-2.63.
