Sillimanite and Hydrogrossular Physical Properties

Sillimanite and Hydrogrossular Chemical Formula

While comparing Sillimanite and Hydrogrossular 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 Sillimanite and Hydrogrossular chemical formula.

• Chemical formula of Sillimanite- Al 2SiO 5Michael O’Donoghue , Gems, Sixth Edition (2006)
• Chemical formula of Hydrogrossular- hydrogrossular Massive vein s of opaque Grossular Garnet that resembles Jade . It is white to light green in color, and may be colored in a white, green, and pink combination. Hydrogrossular is often regarded as a variety of Grossular, but it is scientifi

Sillimanite and Hydrogrossular Specific Gravity

Another important criteria for qualitative analysis of gemstones is Sillimanite and Hydrogrossular Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sillimanite and Hydrogrossular Optical Properties during the identification of gemstone. Specific gravity of Sillimanite is 3.25-3.40 whereas that of Hydrogrossular is 3.25-3.40.
