Sphene and Caledonite Physical Properties

Sphene and Caledonite Chemical Formula

While comparing Sphene and Caledonite 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 Sphene and Caledonite chemical formula.

• Chemical formula of Sphene- CaTiSiO5
• Chemical formula of Caledonite- Pb 5Cu 2(SO 4) 3(CO 3)(OH) 6Anthony et al , Handbook of mineralogy (2001)

Sphene and Caledonite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Sphene and Caledonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sphene and Caledonite Optical Properties during the identification of gemstone. Specific gravity of Sphene is 5.6-5.76 whereas that of Caledonite is 5.6-5.76.
