Why Does White Gold Turn Yellow?

White gold is a popular choice for jewelry, known for its elegant and timeless appearance. However, over time, you may notice that your white gold jewelry starts to turn yellow. This can be a cause for concern, but fear not! There are valid reasons behind this color change.

White gold is actually a mixture of pure gold and other metals, such as copper, silver, nickel, palladium, and zinc. It is the addition of these metals that gives white gold its signature hue. However, the natural color of gold is yellow, so in order to achieve the desired white appearance, white gold is often coated with a layer of rhodium. This rhodium plating gives white gold its bright, lustrous shine.

With time and wear, the rhodium plating on white gold jewelry can gradually wear off, exposing the yellowish color of the underlying gold. This is a natural process and not a sign of poor quality. The rate at which the rhodium plating wears off can vary depending on factors such as the acidity of your skin, the chemical exposure, and the frequency of wear. It is important to note that this yellowing does not indicate a defect or a flaw in the white gold itself.

Key Takeaways:

• White gold is a mixture of pure gold and other metals, giving it a white appearance.
• The yellowing of white gold is caused by the wearing off of the rhodium plating.
• This color change is a natural process and not indicative of poor quality.
• Factors such as skin acidity, chemical exposure, and wear frequency can affect the rate of yellowing.
• The yellowing of white gold can be restored through re-plating by a professional jeweler.

The Composition of White Gold

White gold is a popular choice for jewelry due to its elegant appearance. It is created by combining pure gold with other metals to form an alloy. The specific composition of white gold can vary depending on the jeweler and the desired color of the jewelry. Commonly used metals in white gold alloys include copper, silver, nickel, palladium, and zinc.

These metals not only give white gold its white appearance but also contribute to its overall durability and strength. Copper, for example, adds a reddish tint to the alloy, while nickel and palladium enhance the whiteness. The ratio of these metals to pure gold determines the final color and properties of the white gold.

By carefully selecting and combining these metals, jewelers can create white gold alloys that are beautiful, durable, and suitable for a variety of jewelry designs. The resulting white gold jewelry is prized for its sophisticated and timeless appeal.

The Role of Rhodium Plating

Rhodium plating plays a crucial role in the appearance and protection of white gold jewelry. When white gold is made, it has a natural yellowish color due to the metals used in its composition. To achieve the desired white color, white gold is plated with a thin layer of rhodium, a bright white metal from the platinum family.

The purpose of rhodium plating is twofold. Firstly, it enhances the aesthetics of white gold jewelry by giving it a shiny and reflective surface. This creates a lustrous and eye-catching appearance that many people associate with white gold. Secondly, rhodium plating acts as a protective barrier, preventing the white gold from tarnishing and becoming discolored.

The Process of Rhodium Plating

Rhodium plating is typically applied through a process known as electroplating. The jewelry is submerged in a rhodium solution, and an electric current is passed through it, causing a thin layer of rhodium to bond with the surface of the white gold. This plating process is similar to how chrome is applied to metal surfaces.

It’s important to note that rhodium plating is not permanent. Over time, the plating can wear off, especially on frequently worn items such as rings and bracelets. This can expose the underlying yellowish color of the white gold. However, re-plating can easily restore the bright white appearance of the jewelry.

Regular maintenance, such as cleaning and polishing, can also help prolong the lifespan of the rhodium plating. However, it’s worth noting that not all white gold jewelry requires rhodium plating. Some jewelers may offer white gold alloys that naturally have a whiter color, reducing the need for frequent re-plating.

Maintaining the Beauty of White Gold

To keep white gold jewelry looking its best, it’s recommended to have it professionally cleaned and re-plated periodically, especially if you notice the yellowish color starting to show through. Additionally, avoid exposing white gold to harsh chemicals, such as chlorine and cleaning agents, as these can accelerate the wearing off of the rhodium plating.

By understanding the role of rhodium plating and taking proper care of your white gold jewelry, you can ensure that it retains its bright white appearance and continues to be a stunning piece for years to come.

Factors Contributing to Yellowing of White Gold

White gold may initially have a dazzling white appearance, but over time, it can start to turn yellow. Several factors contribute to this discoloration, and understanding them can help you maintain the beauty of your white gold jewelry.

1. Natural Oils and Acids

The oils and acids naturally present on your skin can react with the metals in white gold, causing it to lose its bright white color. These substances can gradually wear away the rhodium plating, exposing the yellowish hue of the underlying gold.

2. Exposure to Chemicals

Chemicals, such as chlorine found in swimming pools or cleaning agents, can also affect the color of white gold. These chemicals can cause the rhodium plating to deteriorate faster, leading to yellowing of the jewelry.

3. Contact with Lotions and Soaps

Lotions, soaps, and other personal care products can contribute to the yellowing of white gold. These substances can leave residues on your jewelry, which can build up over time and affect its appearance.

It’s important to note that general wear and tear can also impact the color of white gold. As the rhodium plating wears off due to various factors, the underlying yellow color becomes more apparent.

While discoloration is a natural process, there are steps you can take to slow down the yellowing of white gold. Avoid exposing your jewelry to harsh chemicals, remove it before activities that may cause it to come into contact with water or sweat, and regularly clean and polish it to remove any residues. By following these preventative measures, you can help maintain the beautiful white appearance of your white gold jewelry.
