Zircon is a zirconium silicate mineral. It is the principle source of the element zirconium (Zr) 1  usually small and inclusion-rich.  Zircon is highly resistant to weathering (maybe the most resistant of any mineral) This, and its high specific gravity, favor its concentration in placer deposits and alluvial gem gravels.
Zirconium is located below titanium, which it resembles, in the periodic table. Below zirconium is hafnium, a chemical twin of zirconium. An important use of zirconium is in nuclear power plants. Its most important compound is zircon, which has a number of industrial applications.Zircon can also be obtained in gemstone quality. A gemstone is a mineral that can be cut and polished and used in jewelry or art.he two most common compounds made are zircon (zirconium silicate) and zirconia (zirconium oxide). Naturally occurring zircon is in demand as a gemstone. It is polished, cut, and used for jewelry and art.
