Common Opal and Actinolite Chemical Formula
While comparing Common Opal and Actinolite 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 Common Opal and Actinolite chemical formula.
- Chemical formula of Common Opal- SiO 2 · nH 2OWalter Schumann , Gemstones of the world (2001)
- Chemical formula of Actinolite- Ca 2(Mg,Fe) 5Si 8O 22(OH) 2Ulrich Henn and Claudio C.
Common Opal and Actinolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Common Opal and Actinolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Common Opal and Actinolite Optical Properties during the identification of gemstone. Specific gravity of Common Opal is 3.00 whereas that of Actinolite is 3.00.
