Yes, black gold can fade over time.
Black gold, particularly when created by applying a black coating like rhodium plating onto gold, is subject to wear and tear that can affect its appearance. Like many coated metals that develop a natural patina, the surface layer responsible for the black color is not permanent.
Understanding Why Black Gold Fades
The depth and permanence of black gold's color depend heavily on the method used to achieve the black hue. One common method involves applying a layer of black rhodium. As stated in the reference, "Like all metals that are said to be rhodium-plated, black gold is a metal that develops a patina."
The reference explicitly confirms that the applied layer will fade: "With time, rubbing and shocks, the rhodium layer applied to black gold will fade."
Factors Contributing to Fading
The fading process is primarily caused by interaction with the environment and daily use. The main culprits include:
- Time: Natural aging and chemical reactions over long periods.
- Rubbing: Friction from contact with skin, clothing, other jewelry, and surfaces.
- Shocks: Impacts and knocks that can chip or wear away the surface layer.
These factors gradually wear down the black coating, revealing the underlying gold color and creating a faded or uneven appearance.
Is Fading Normal?
It's important to understand that for black gold created with surface treatments like rhodium plating, fading is considered a normal process. The reference confirms, "Don't worry, this is not serious and is quite normal!" It's a characteristic of the material and its finish, akin to how a patina develops on other metals.
Maintaining and Restoring Black Gold
While fading is normal, there are ways to slow it down and options for restoration:
- Careful Wear: Avoid wearing black gold jewelry during activities where it might be subject to excessive rubbing or impacts.
- Gentle Cleaning: Clean with mild soap and water and dry thoroughly with a soft cloth. Avoid harsh chemicals or abrasive cleaners.
- Re-plating: If the fading becomes significant, the black rhodium layer can often be reapplied by a professional jeweler to restore the original color.
Understanding that the black color is often a surface treatment helps manage expectations and appreciate the unique aging process of your black gold pieces.
| Factor | Effect on Black Rhodium Plating |
|---|---|
| Time | Natural aging, contributes to wear |
| Rubbing | Wears away the surface layer by friction |
| Shocks | Can chip or abrade the coating |
