Thulite and Serandite Chemical Formula
While comparing Thulite and Serandite 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 Thulite and Serandite chemical formula.
- Chemical formula of Thulite- Ca2Al3(SiO4)3(OH)
- Chemical formula of Serandite- Na(Mn2+ ,Ca) 2Si 3O 8(OH)Michael OâDonoghue , Gems, Sixth Edition (2006)
Thulite and Serandite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Thulite and Serandite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Thulite and Serandite Optical Properties during the identification of gemstone. Specific gravity of Thulite is 3.52 whereas that of Serandite is 3.52.
