The Revolutionary Clear Coating for Cubic Zirconia: A Game-Changer in the Jewelry World

In the ever-evolving world of jewelry, innovation is key. Recently, a remarkable development has emerged that has the potential to revolutionize the industry: a clear coating that can be applied to cubic zirconia, making it virtually indistinguishable from a diamond when tested with a Diamond Selector 2. Let’s delve into what this means for jewelry enthusiasts and how it impacts the market.
What is Cubic Zirconia?

Cubic zirconia (CZ) is a synthetic gemstone that has been popular for decades due to its stunning visual similarity to diamonds and its affordability. While it shares many optical properties with diamonds, such as brilliance and fire, it is fundamentally different in composition and hardness.
The Diamond Selector 2

The Diamond Selector 2 is a widely used tool in the jewelry industry. It tests the thermal conductivity of gemstones to distinguish diamonds from other materials. Since diamonds have high thermal conductivity, they can be easily identified using this tool.
The Innovation: Clear Coating for Cubic Zirconia

The invisible coating applied to cubic zirconia tests as a diamond

A new technological breakthrough has introduced a clear coating that can be applied to cubic zirconia. This coating enhances the thermal conductivity of CZ to the point where it can pass as a diamond when tested with a Diamond Selector 2. This is a significant development because it challenges one of the primary methods used to authenticate diamonds.
Implications for the Jewelry Market

This is such a close guarded secret amongst jewelers in the industry It has taken me months to finally confirm that it exists.

Consumer Awareness:
Transparency is Key: It’s crucial for consumers to be aware of this innovation. While cubic zirconia with the coating can mimic diamonds in tests, they are not diamonds. Jewelry sellers must disclose the nature of these gemstones to maintain trust and integrity.

Potential for Misuse:
Ethical Considerations: Unfortunately, there is a potential for unscrupulous sellers to misrepresent cubic zirconia as diamonds, especially in online marketplaces where direct examination is not possible. Buyers should ensure they purchase from reputable sources.

Impacts on the Industry:
Jeweler Training: Jewelers and appraisers will need to stay updated on this technology to accurately assess and communicate the nature of the gemstones they are dealing with. This includes adopting new methods for distinguishing between diamonds and coated cubic zirconia.

 

Please pass the word this deception must be stopped. It is our duty as jewelers to spread the word as fast as we can.

Conclusion

The introduction of a clear coating for cubic zirconia that allows it to pass diamond selector tests is a testament to the ingenuity within the jewelry industry. However, it’s important to approach such innovations with caution. If you come across moissanite or diamond listings for $5.00 on platforms like Alibaba, rest assured these are not genuine. From my experience, the coating on these stones only lasts a few weeks before wearing off, at which point they no longer test as diamonds but as pretty glass. Unfortunately, I spent significantly more than a few dollars before realizing this. If it seems too good to be true, it likely is.
This underscores the need for transparency and ethical practices in the jewelry market. As we embrace these advancements, it’s essential to stay informed and make conscientious choices, ensuring that the beauty of jewelry continues to be matched by the integrity of its market.
