Although they are not real diamonds, cubic zirconia stones possess many of the same traits of more valuable gems. To preserve their shine and beauty, cubic zirconia gems should be cleaned monthly. Cleaning is a quick, simple process that involves scrubbing cubic zirconia with mild dish soap and water. When you're done, your jewelry should look shiny and new.

- If you don't have a spare toothbrush on hand, cubic zirconia can also be cleaned with a soft cosmetic brush. A brush used for eye shadow, for example, would work well.

Gently set your cubic zirconia in the water/detergent mixture so it's fully submerged. There is no precise amount of soaking time required, but let the gem sit for at least a couple of minutes.^{[6]

If both cleaning and soaking do not restore cubic zirconia's shine, it's time to seek professional treatment. A high-pressure steam clean may be needed, which should be done by a professional jeweler.^{[8]

Synthetic cubic zirconia is a man-made product. Cubic zirconia usually comes to you already polished by automatic machines during the cutting process. In most cases, the machines work the stone into the same styles as diamonds.
