White gold is an alloy that captures the glamour of gold in a palette preferred by those who appreciate a silvery appearance. It's especially popular for jewelry, providing an affordable alternative to platinum. However, over time, you might notice changes in its luster and color, leading to the common question of whether white gold can tarnish. The answer is yes; white gold can tarnish, but it's a bit more complex than tarnishing seen in other metals.
Tarnishing of white gold occurs due to a reaction with various chemicals, both at home and in the environment. Typically, this metal is plated with rhodium to improve its whiteness, as the underlying alloy can have a yellowish tinge due to the presence of other metals that are mixed with gold to create the alloy. This rhodium plating can wear off, exposing the actual color of the white gold beneath. Additionally, exposure to certain substances or chemicals can lead to discoloration or a loss of sheen.
Maintenance and care are essential when it comes to white gold. Whether it's the oils on your skin, makeup, or exposure to harsh cleaning chemicals, these all can affect the appearance of your white gold jewelry. Regular cleaning, polishing, and occasional re-plating of white gold can help preserve its beauty and prevent the visible signs of wear that might be mistaken for tarnish. Understanding the properties of white gold and how it interacts with your environment will ensure that your white gold jewelry remains as stunning as the day you bought it.
Composition of White Gold
White gold is more than just a precious metal; it's a blend of gold with other metals that create its unique appearance. In its unembellished state, white gold possesses a distinctive color that is altered by both its composition and treatment.
Alloy Metals and Purity
Alloys: White gold is an alloy, which means that it is made up of gold and at least one other metal. Common alloy metals combined with gold include nickel, silver, and zinc. These additions are necessary to alter the color of pure gold and achieve that sought-after silver tone that characterizes white gold.
- Nickel: Known for its hardness.
- Silver and Zinc: Contribute to the metal's strength and color.
Purity: Gold purity is traditionally measured in karats, with pure gold being 24k. However, because pure gold is too soft for jewelry use, it is mixed with other metals to create more durable alloys:
- 14k Gold: Contains 58.3% gold and 41.7% alloy metals.
- 18k Gold: Has 75% gold, making it purer and more valuable than 14k, but also softer.
- 10k Gold: With 41.7% gold, this is less pure but more durable than higher karat options.
Rhodium Plating
What is Rhodium Plating? Rhodium plating is a process used to give white gold a highly reflective white surface. Rhodium is a platinum group metal, prized for its exceptional shine and durability.
Purpose in White Gold:
- Provides a protection layer against scratches and tarnishing.
- Enhances the white color of the gold.
Rhodium plating can wear off over time, requiring re-application to maintain the jewelry's luster. It's essential to understand that the need for re-plating depends on the wear and tear of the individual piece.

Color and Luster
Your white gold’s color can vary depending on the alloys used and the plating finishes applied. Generally, it has a silvery hue with a high luster, which is often enhanced by rhodium plating to give it a bright, reflective finish. However, over time, exposure to various substances or chemicals can lead to slight discoloration, which is why some white gold jewelry may eventually require re-plating to maintain its quality and shine.
The Tarnishing Process
When discussing white gold, you may wonder about its resilience to tarnishing. Tarnishing is a form of corrosion that affects metals when they undergo chemical reactions with substances in their environment. Specifically for white gold, the tarnishing process not only affects the appearance but can also provide insights into the material's composition and durability.
Factors Influencing Tarnish
Several factors can accelerate the tarnishing of white gold. Chemicals such as those found in perfume, soap, and cleaning products may cause white gold to tarnish more quickly. Environmental factors like humidity and sweat can also expedite the process, as moisture triggers oxidation. Chlorine, often found in swimming pools and cleaning agents, is particularly aggressive and can lead to severe discoloration and structural damage if your white gold is exposed to it frequently.
Tarnishing is typically seen as darkening or discoloration, which is a result of the surface reacting and forming a layer of tarnish. The metals in white gold might oxidize when exposed to air and moisture, leading to tarnishing. The rate at which tarnishing occurs in white gold can also indicate the purity and the type of alloys used in the composition of the jewelry.
Comparison to Other Metals
White gold is an alloy containing gold and other white metals to enhance its strength and alter its color. The tarnish resistance of white gold compared to that of other metals varies significantly. For instance, pure gold does not tarnish because it does not oxidize in air or water. However, the other metals mixed with gold to create white gold, such as nickel or palladium, can oxidize, which introduces the possibility of tarnish.
In comparison, metals like silver are notorious for their susceptibility to tarnish. Silver reacts with sulfur compounds present in the air, leading to a distinctive black tarnish. White gold is generally more resistant to tarnish than silver due to its alloying elements and protective rhodium plating often applied to it. However, this plating may wear off over time, exposing the base metals to conditions that may lead to tarnish.
