Petalite and Citrine Chemical Formula
While comparing Petalite and Citrine 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 Petalite and Citrine chemical formula.

Petalite and Citrine Specific Gravity
Another important criteria for qualitative analysis of gemstones is Petalite and Citrine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Petalite and Citrine Optical Properties during the identification of gemstone. Specific gravity of Petalite is 2.65 whereas that of Citrine is 2.65.
