The most common way to change the color of yellow gold jewelry is through rhodium plating.
Here's a breakdown of the process and what to consider:
Rhodium Plating: A Temporary Color Change
Rhodium is a hard, silvery-white metal belonging to the platinum family. It's highly reflective and resistant to tarnish, making it ideal for plating jewelry.
-
The Process: Rhodium plating involves coating the yellow gold item with a thin layer of rhodium. This creates a bright white appearance, effectively masking the yellow gold underneath.
-
Durability: Rhodium plating is not permanent. The rhodium layer will wear off over time, revealing the yellow gold beneath. The rate at which it wears down depends on factors such as:
- Frequency of wear
- Thickness of the plating
- Contact with abrasive surfaces or chemicals (e.g., lotions, cleaning products)
-
Maintenance: To maintain the white color, rhodium plating needs to be reapplied periodically. This is a relatively inexpensive service offered by most jewelers.
Alternatives (More Permanent Solutions):
While rhodium plating is the most common method, other approaches offer more permanent color changes, but involve more significant alterations to the jewelry:
-
Remelting and Alloying: The gold could be remelted and mixed with different alloy metals to create white gold. However, this is essentially creating new gold rather than simply changing the existing yellow gold's color. This method is best suited if you're completely changing the design of the jewelry.
-
Surface Treatments (Less Common): Some less common surface treatments exist, but are not typical for everyday jewelry. These may involve techniques that alter the surface structure of the gold, but can affect the durability and integrity of the item. Due to their complexity and potential risks, consulting a skilled jeweler is critical if considering these methods.
Summary:
Rhodium plating is the go-to method for temporarily changing the color of yellow gold to white gold. While it requires periodic reapplication, it’s a simple and cost-effective solution. More permanent changes require more extensive work and should be carefully considered.
