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

Tremolite and Howlite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Tremolite and Howlite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Tremolite and Howlite Optical Properties during the identification of gemstone. Specific gravity of Tremolite is 2.45-2.58 whereas that of Howlite is 2.45-2.58.
