Topaz and Scapolite Chemical Formula
While comparing Topaz and Scapolite 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 Topaz and Scapolite chemical formula.
- Chemical formula of Topaz- Al2SiO4(F,OH)2
- Chemical formula of Scapolite- Na 4Al 3Si 9O 24Cl to Ca 4Al 6Si 6O 24(CO 3,SO 4)Walter Schumann , Gemstones of the world (2001) More from other references
Topaz and Scapolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Topaz and Scapolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Topaz and Scapolite Optical Properties during the identification of gemstone. Specific gravity of Topaz is 2.58-2.74 whereas that of Scapolite is 2.58-2.74.
