Garnet and Howlite Chemical Formula
While comparing Garnet 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 Garnet and Howlite chemical formula.
- Chemical formula of Garnet- Garnet is a series of several different minerals with unique chemical formulas.
- Chemical formula of Howlite- Ca 2B 5SiO 9(OH) 5Michael OâDonoghue , Gems, Sixth Edition (2006) More from other references
Garnet and Howlite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Garnet and Howlite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Garnet and Howlite Optical Properties during the identification of gemstone. Specific gravity of Garnet is 2.45-2.58 whereas that of Howlite is 2.45-2.58.
