Revealing the Glare: Does Cubic Zirconia Tarnish Over Time?

does cubic zirconia tarnish

Because cubic zirconia is more affordable and has more sparkle than diamonds, it has become a popular substitute for diamonds in jewelry. But concerns regarding its longevity frequently persist; one well-known one is: does cubic zirconia tarnish? It’s important to investigate the characteristics of cubic zirconia, its makeup, and the variables that could affect its look over time in order to answer this question.

Knowing About Cubic Zirconia

Cubic zirconia, sometimes shortened to CZ, is a man-made gemstone designed to emulate the brilliant properties of diamonds. CZ was discovered in the 1930s and became well-known in the jewelry industry because of its exceptional brilliance and toughness. CZ, which is made of zirconium dioxide, has an amazing Mohs hardness of 8.5 to 9, which means it is resistant to abrasions and scratches.

Does Zirconia Cubic Tarnish?

The actual cubic zirconia does not tarnish over time, in contrast to some metals that may. Generally speaking, “tarnish” describes the dulling or darkening of metal surfaces, which is frequently caused by oxidation. Nevertheless, cubic zirconia doesn’t go through the same chemical processes that cause tarnishing because it is a crystalline compound rather than a metal.

A Few Things That Affect How Cubic Zirconia Looks

While it’s true that does cubic zirconia tarnish-resistant, external factors can still impact its appearance over time. Among these are:

Environmental Exposure

A cubic zirconia’s sparkle may be impacted by exposure to a variety of environmental factors. The gemstone’s surface may become dulled by harsh chemicals, as those in some beauty items or cleaning supplies for the home. It is best to take off cubic zirconia jewelry before participating in activities that require chemical exposure in order to preserve its brightness.

Abrasion and Scratching

So does cubic zirconia tarnish? Although cubic zirconia has a high degree of hardness, damage can still occur. The clarity and brightness of the gemstone may be compromised by severe scratching or abrasion. To reduce the possibility of scratches, cubic zirconia jewelry should be stored apart from other things.

Storage Conditions

Maintaining the shine of cubic zirconia requires proper storage. Preserving jewelry in a cool, dry area away from direct sunshine can help stop the appearance of gemstones from deteriorating. Furthermore, cubic zirconia can be shielded from scratches and abrasions by utilizing soft pouches or jewelry boxes lined with cloth.

Cleaning Techniques

Although cleaning cubic zirconia is not too difficult, improper techniques might affect the material’s look. For the removal of oils and filth, a gentle cleaning with a soft, damp cloth is typically sufficient. Steer clear of using harsh chemicals or abrasive materials as they might dull the gemstone’s surface and reduce its shine.

Setting Material

So finally, does cubic zirconia tarnish? The overall durability of cubic zirconia can also be affected by the setting material used for it. Fine settings, such those crafted from platinum, gold, or sterling silver, give the gemstone a safe haven. Over time, lower-quality settings could erode and change how the cubic zirconia looks.


So the answer of the question- does cubic zirconia tarnish is cubic zirconia does not tarnish on its own because it is not metal. To maintain the shine of cubic zirconia jewelry, however, constant upkeep and awareness of environmental factors are required. By avoiding abrasives, strong chemicals, and extreme temperatures, cubic zirconia can last for years. People looking for a beautiful, affordable diamond alternative still choose cubic zirconia. Due to their awareness of cubic zirconia’s appearance and durability, jewelry aficionados can confidently wear them.
