Rose Quartz and Alunite Chemical Formula
While comparing Rose Quartz and Alunite 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 Rose Quartz and Alunite chemical formula.
- Chemical formula of Rose Quartz- SiO2
- Chemical formula of Alunite- KAl3(SO4)2(OH)6
Rose Quartz and Alunite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Rose Quartz and Alunite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rose Quartz and Alunite Optical Properties during the identification of gemstone. Specific gravity of Rose Quartz is 2.6-2.9 whereas that of Alunite is 2.6-2.9.
