8. Cubic Zirconia FAQ

What is Cubic Zirconia Made Of?

Cubic zirconia is constructed from an amalgamation of zirconium oxide as well as other minerals such as calcium and magnesium. Its production begins by melting these components in a metal chamber and then raising the temperature to almost 5,000 degrees Fahrenheit.

Removing a CZ from the metal chamber initiates the process of crystal formation. Then, the gem is cut into desired shapes like emerald-cut, oval-cut, pear-cut and so forth.

Cubic zirconia can be made available in different colors like pink, blue and green. Additionally, manufacturers are capable of producing cubic zirconia of any shade you can imagine.

To create the desired effect while manufacturing cubic zirconia, different impurities can be mixed into the product. Iron and copper are added to make it yellow, while erbium, europium or holmium produce pink cubic zirconia.
