Zircon is a nesosilicates group mineral. Its corresponding chemical formula is ZrSiO4. The name derives from the Persian zargun, meaning “gold-hued”. Zircon is a popular gemstone that has been used for nearly 2000 years.
The crystal structure of zircon is a tetragonal crystal system with 7.5 hardness according to the Mohs Hardness scale. Zircon is also very resistant to heat and corrosion and known as Insoluble gemstone. This Uniaxial (+) mineral Specific gravity is 4.6–4.7. It’s heavy more than such as Sapphire, chrysoberyl, Garnets, spinels. Gem Businessmen use these physical properties to identify zircons from other gemstones.
