• Chemical formula of Starlite- ZrSiO 4Michael O’Donoghue , Gems, Sixth Edition (2006)

Austinite and Starlite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Austinite and Starlite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Austinite and Starlite Optical Properties during the identification of gemstone. Specific gravity of Austinite is 3.91-4.73 whereas that of Starlite is 3.91-4.73.
