Rhyolite and Ruby Physical Properties

Rhyolite and Ruby Chemical Formula

While comparing Rhyolite and Ruby 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 Rhyolite and Ruby chemical formula.

• Chemical formula of Rhyolite- 70% SiO2, Al2O3, Na2O, K2O
• Chemical formula of Ruby- Al ₂ O ₃

Rhyolite and Ruby Specific Gravity

Another important criteria for qualitative analysis of gemstones is Rhyolite and Ruby Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rhyolite and Ruby Optical Properties during the identification of gemstone. Specific gravity of Rhyolite is 3.97-4.05 whereas that of Ruby is 3.97-4.05.
