Cubic zirconia. Cubic zirconia (abbreviated CZ) is the cubic crystalline form of zirconium dioxide (ZrO 2). The synthesized material is hard and usually colorless, but may be made in a variety of different colors. It should not be confused with zircon, which is a zirconium silicate (ZrSiO 4).
Cubic zirconia (zirconium oxide) is a synthetic gemstone. The colourless stones, when cut, resemble diamonds. Zircon mixed with vanadium or praseodymium makes blue and yellow pigments for glazing pottery.
Cubic zirconia - a girl's best friend? Zirconium is abundant in S-type stars in which heavier elements are formed by neutron capture. Traces of the element are also present in the Sun, and rock brought back from the moon was found to have a surprisingly high zirconium content.
