Not zirconium metal, but zirconium dioxide (zirconia) - ZrO2.
Simply speaking CZ is made via crystallisation. In this process, the compound is heated up until it melts and then allowed to cool at which point it reforms into its structured crystal form.
The amazing thing about CZ is that it uses the 'skull crucible' technique in which the outside of the CZ sample does not melt but the inside does. The outside then acts as a container for the melted inside part. The reason this approach is used is because there are few other containers that stay solid at the super-2000 degrees centigrade required to melt CZ!

Does cubic zirconia contain lead?
Only as an impurity, in traces. The correct term is cubic zirconia (ZrO2), not cubic zirconium (Zr).
Is cubic zirconia a mineral?
Minerals are, by definition, naturally occurring. Since cubic zirconia is synthesized in a lab, it is not considered a mineral.
Why is cubic zirconia not a mineral?
Geologists define minerals as occurring naturally. As cubic zirconia is synthesized in a lab, it is not considered a mineral
How can chemical symbols show that cubic zircon is not a diamond?
You'd find out what cubic zirconia is conposed of, and compare it to what diamonds are composed of, and since they are composed of different things, their chemical symbols will be different.
What are the differences between a diamond necklace and a cubic zirconia necklace?
The differences between a diamond and a cubic zirconia necklaces are the differences in the precious rocks used. What makes the difference in the necklace are the properties of the diamond and a cubic zirconia. The diamonds is stiffer and lighter and obviously more expensive.
How does the price of a cubic zirconia ring compare to a diamond ring?
Cubic zirconia rings are much less expensive than diamond rings. A cubic zirconia ring may cost around $700 while a diamond ring can cost upwards of $40,000. Cubic zirconia is a much less valuable stone than diamond is and cubic zirconia rings are priced as such.

Where can cubic zirconia jewelry be purchased offline?
Cubic zirconia can be purchased at a variety of offline retailers. Many big-box discount stores such as Target, Wal-Mart, K-Mart, and Kohls carry cubic zirconia jewelry.
What is diamonesk?
Diamonesk stones are used in personalized engagement and wedding ring sets. Diamonesk is much more brilliant and shiny than cubic zirconia and doesn't dull with use as cubic zirconia does.
Which looks more like the real thing, cubic zirconia or rhinestones ?
Cubic zirconia more closely resembles diamonds than rhinestones. Cubic zirconia are hard, durable and can't be distinguished unless under a trained eye of jewelry professional.
Can you super glue cubic zirconia?
Yes, you can super glue cubic zirconia. It's an excellent way to stick small gems back in the holder.
What is the price range of cubic Zirconia necklaces?
The price range for cubic zirconia necklaces is quite large. Prices range from under $10 at discount/big box stores and can reach over $500 depending on the size and metal that the cubic zirconia is set in.
What are the most common colors of cubic zirconia?
Don't confuse zirconium (Zr) with zirconia (ZrO2). Pure (without dopants) zirconia is incolor and transparent.
