Cubic Zirconia. Cubic zirconia (CZ), a diamond simulant, is not only the oldest diamond substitute, but also the most popular. Composed of zirconium oxide (ZrO 2) the mineral is extremely rare in natural form. Discovered by German mineralogists in 1937, zirconium wasnât considered economically feasible.ubic zirconia possesses less brilliance (less sparkle), but has more fire (flashes of rainbow color.) CZ is also very hard, not quite as hard as a diamond, but like a diamond can scratch glass.
