Cubic zirconia does not rust, but the jewelry setting can. Inexpensive metals such as brass, gold-plated alloys, and sterling silver often rust over time due to exposure to oxygen in the air and water.

Does cubic zirconia tarnish?

Depending on the material of your jewelry setting, it may start to dull or tarnish over time. Any cubic zirconia jewelry set in gold, silver, or platinum should be cleaned using a high-quality, professional jewelry cleaner.

Can you wear cubic zirconia in the shower?

Take your Cubic Zirconia jewelry off before showering. Repeated exposure to water will ruin this jewelry along with its gemstones. The only time that you can get your Cubic Zirconia jewelry wet is when you are cleaning it. Even then, it should only be for a short period.
