Howlite and Euclase Chemical Formula
While comparing Howlite and Euclase 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 Howlite and Euclase chemical formula.

Howlite and Euclase Specific Gravity
Another important criteria for qualitative analysis of gemstones is Howlite and Euclase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Howlite and Euclase Optical Properties during the identification of gemstone. Specific gravity of Howlite is 3.08-3.12 whereas that of Euclase is 3.08-3.12.
