Glaucophane and Carnelian Chemical Formula
While comparing Glaucophane and Carnelian 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 Glaucophane and Carnelian chemical formula.
- Chemical formula of Glaucophane- [ ]Na2(Mg3Al2)Si8O22(OH)2
- Chemical formula of Carnelian- SiO2
Glaucophane and Carnelian Specific Gravity
Another important criteria for qualitative analysis of gemstones is Glaucophane and Carnelian Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Glaucophane and Carnelian Optical Properties during the identification of gemstone. Specific gravity of Glaucophane is 2.58-2.64 whereas that of Carnelian is 2.58-2.64.
