Chrysoprase and Phosphosiderite Chemical Formula
While comparing Chrysoprase and Phosphosiderite 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 Chrysoprase and Phosphosiderite chemical formula.
- Chemical formula of Chrysoprase- SiO2 (with a high level of nickel impurities )
- Chemical formula of Phosphosiderite- Fe3+ PO 4 · 2H 2OAnthony et al , Handbook of Mineralogy (2001)
Chrysoprase and Phosphosiderite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Chrysoprase and Phosphosiderite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chrysoprase and Phosphosiderite Optical Properties during the identification of gemstone. Specific gravity of Chrysoprase is 2.74-2.76 whereas that of Phosphosiderite is 2.74-2.76.
