Zircon, also known as zircon silicate (ZrSiO₄), is found in ancient mineral sand deposits. In the form of crystal sands, zircon is typically brown, but could also vary from colourless to yellow-golden, pink and red to blue and green.

Zircon is one of the two core product streams from ‘mineral sands’, the other being titanium minerals (ilmenite, leucoxene and rutile).
