What is PVD Coating?
By: Leslie H.

To understand PVD coating, it's important to consider its background. PVD, or Physical Vapor Deposition, is a coating method initially used in high-tech applications such as NASA, and only recently applied to jewelry. Before PVD, electroplating was the norm in jewelry coating.

Originally used in aerospace and medical applications, PVD coating involves the deposition of thin layers of metals such as gold, silver, or platinum onto a surface through a vacuum process. This technique creates a bond at the molecular level, ensuring a finish that is as durable as it is beautiful. Electroplating involved thoroughly cleaning the jewelry to remove any dirt or grime, which could interfere with the coating process. The piece was then immersed in a chemical solution containing the coating metal, and electricity was used to bind the metal to the jewelry.

What is PVD Gold?

PVD stands for Physical Vapor Deposition. In this process, a piece of jewelry is first cleaned of any surface debris. The jewelry is then placed in a vacuum chamber. A metal, chosen for its color and properties, is vaporized in the chamber. The vaporized metal atoms then bond to the jewelry's surface, creating a thin and incredibly durable coating.

PVD coating allows for a wide range of colors, from classic gold and silver to vibrant hues and unique tones. This versatility opens up new avenues for designers and consumers alike, seeking personalized and trendy jewelry pieces.

Various methods can produce PVD Gold, but the underlying scientific principles are similar. The result is jewelry that feels smooth and appears lustrous. PVD-coated gold is resistant to wear from external factors like sweat and perfume.
