PVD (Physical Vapor Deposition) coating is a high-tech process that applies a thin, durable, and long-lasting metallic film onto a jewelry’s base metal.
It is often used to plate stainless steel and other strong, stable metals.
How PVD coating works
The PVD process is performed in a vacuum chamber and works at the atomic level, which creates a stronger, more resilient bond than traditional electroplating.
- Jewelry is thoroughly cleaned to remove all contaminants.
- It is placed inside a vacuum chamber. Air is removed to create a high-vacuum environment.
- A solid material, such as gold or titanium, is vaporized using high heat or plasma.
- The vaporized metal atoms condense onto the jewelry’s surface, forming a thin, hard coating that is molecularly bonded to the base metal.
PVD vs. traditional electroplating
PVD is widely considered superior to traditional electroplating for jewelry, especially when using durable base metals like stainless steel.
| Feature | PVD Coating | Traditional Electroplating |
|---|---|---|
| Durability | Creates a molecular bond, making it more resistant to scratches, corrosion, and fading. | Offers a thinner, weaker bond that is more prone to chipping and wearing off over time. |
| Hypoallergenic properties | Safe for sensitive skin because it creates a solid barrier that prevents contact with the underlying base metal. | The thin plating can wear away, exposing irritating base metals like nickel. |
| Color quality | Produces a more consistent and uniform color finish. | Can result in an uneven or patchy color, particularly on intricate designs. |
| Environmental impact | Considered more eco-friendly as it is a “dry” process that uses no harsh chemicals and produces minimal waste. | Often uses chemical baths containing toxic substances, which require complex wastewater treatment. |
Is PVD jewelry a good choice?
PVD jewelry offers an excellent balance of beauty, durability, and affordability. It is waterproof, tarnish-resistant, and maintains its shine for years, especially with proper care, making it a great option for daily wear. However, some brands exaggerate the coating’s longevity, and it will eventually show signs of wear over time.
