Zircon (including hyacinth or yellow zircon) is a mineral belonging to the group of nesosilicates. Its chemical name is zirconium silicate and its corresponding chemical formula is ZrSiO4. Zircon is a mineral, occurring in tetragonal crystals, yielding brilliant clear gemstones called "cubic zircons" or "cubic zirconia". A cheap alternative to diamond.
