In the same year as Klaproth detected uranium, he also isolated zirconia or zirconium oxide from the mineral variously known as zircon, hyacinth, jacynth and jargoon; but he failed to obtain the metal, this being first accomplished some years later by Berzelius, who decomposed the double potassium zirconium fluoride with potassium.
Zirconia Overview Zirconia is an ionic ceramic, zirconium oxide.
Cubic zirconia (often abbreviated CZ) is a lab-created crystalline cubic form of zirconium oxide stabilized with small quantities of other minerals, typically yttrium or calcium.
Diamonds can be found in many different colors, and so can CZ, depending on what different mineral oxides have been added to the zirconium oxide during crystal stabilization and cooling.
