White gold is one of the most popular choices in the world of jewelry, offering a sleek, modern look that complements a wide variety of styles. Whether you’re considering a white gold engagement ring, a necklace, or a pair of earrings, it’s important to understand what makes this material unique. In this guide, we’ll dive into everything you need to know about white gold—from its composition and making process to its pros, cons, and maintenance tips.
Understanding White Gold
What is white gold?
White gold is not a naturally occurring metal; it’s an alloy made by mixing pure yellow gold with other metals like palladium, platinum, silver, and nickel. These metals give white gold its distinctive silvery-white hue while also improving its strength and durability.
Unlike yellow gold, which retains its natural color, white gold's color comes from the combination of metals used in its creation. This transformation into a cooler tone makes it a versatile option for many types of jewelry, particularly when a sleek, minimalist look is desired.

How White Gold Is Made
The process of making white gold begins with pure yellow gold, which is too soft for everyday wear on its own. To increase its durability and change its color, jewelers mix the yellow gold with white metals such as:
Palladium: Adds strength and a bright white finish.
Platinum: Known for its durability and hypoallergenic properties.
Silver: Adds a more subtle sheen while maintaining strength.
Nickel: Commonly used for durability but can cause allergic reactions in some people.
Once these metals are combined, the resulting alloy takes on a silver-like color, but it often has a slight yellowish tint. This is where rhodium plating comes in, as it is applied to give white gold its brilliant, reflective, and completely white appearance.
Role of Rhodium Plating
One of the key finishing touches on white gold jewelry is rhodium plating. Rhodium, a rare and valuable metal, is used to coat white gold to achieve a shiny, bright-white finish that enhances the beauty of the piece.
Why is rhodium plating necessary?
Appearance: White gold without rhodium plating may have a slight yellowish tint, depending on the alloy composition. Rhodium gives it the dazzling, pure white look that people associate with white gold.
Durability: Rhodium plating helps protect the underlying gold from scratches, dents, and other forms of wear and tear.
However, rhodium wears off over time, especially with frequent use. When the plating wears away, the underlying yellowish tint of the alloy can become more visible. Luckily, rhodium re-plating is a simple and relatively inexpensive process that restores the jewelry’s original shine.
Karat Levels and Alloys
When purchasing white gold, you’ll often encounter terms like "18K" or "9K," which refer to the karat level of the gold. This is a measure of how much pure gold is in the alloy. The higher the karat number, the higher the percentage of pure gold in the mix.
18K White Gold: Contains 75% gold and 25% alloy metals. It’s more expensive and has a richer gold content but is slightly softer than lower-karat options.
14K White Gold: Contains 58.3% gold and 41.7% alloy metals. A popular choice for engagement rings and wedding bands due to its balance of affordability and durability.
9K White Gold: Contains 37.5% gold and a higher percentage of alloy metals, making it a more budget-friendly option but less rich in gold.
The composition of white gold also influences its final appearance, with some alloys producing a brighter white color than others. Be aware that nickel is sometimes used in lower-karat white gold, which can cause allergic reactions in certain individuals.
For those prone to allergies, some jewelers offer nickel-free white gold options, using metals like palladium instead. If you’re looking for other gold alternatives, gold plated vs. gold filled jewelry can also be a great option to explore, especially for those seeking a more affordable piece.
Pros and Cons of White Gold
Just like any metal, white gold comes with its own set of benefits and drawbacks. Let’s break them down to help you make an informed decision.
Pros of White Gold:
Elegant Appearance: White gold has a sophisticated, modern look that resembles platinum but is much more affordable. Its neutral tone complements all skin tones and outfits.
Durable and Strong: Thanks to the metals used in the alloy, white gold is more durable than pure gold. This makes it ideal for everyday wear, especially for rings and bracelets.
Affordable Alternative to Platinum: While white gold and platinum look similar, white gold tends to be more affordable, making it a popular choice for those wanting a luxurious look without the platinum price tag.
Perfect for Diamond Settings: The bright white finish of rhodium-plated white gold enhances the sparkle of diamonds, making it a popular choice for engagement rings.
Cons of White Gold:
Rhodium Maintenance: Over time, rhodium plating wears off, requiring periodic re-plating to maintain the piece’s appearance. If neglected, the jewelry can develop a yellowish tint.
Allergy Concerns: White gold made with nickel can cause skin irritation or allergic reactions in some individuals. Always check with your jeweler for nickel-free options.
Not Hypoallergenic: While more durable than silver, white gold is less hypoallergenic than platinum or palladium, both of which are commonly used for people with sensitive skin.
If you’re looking for an even more durable option, consider sterling silver, which offers a strong alternative to white gold with a similar appearance, though it requires more regular polishing to prevent tarnishing.
Why White Gold Turns Yellow Over Time
One of the most common questions about white gold is why it sometimes develops a yellow tint. This happens when the rhodium plating wears off, exposing the underlying alloy, which can have a faint yellowish hue due to the gold content.
To maintain the bright white look, white gold jewelry needs to be re-plated with rhodium periodically. This is usually done every 12 to 18 months, depending on how often the jewelry is worn and how much wear it experiences.
How to Identify White Gold
If you’re unsure whether a piece of jewelry is made from white gold, there are a few ways to identify it:
Hallmarks: Look for a hallmark on the inside of rings or on the clasp of necklaces and bracelets. It will usually be stamped with a number indicating the karat level (e.g., “18K” or “750” for 75% gold).
Color and Shine: White gold has a bright, reflective finish thanks to rhodium plating. If it looks slightly yellow, it may be in need of re-plating.
Weight: White gold is lighter than platinum but heavier than silver. If the piece feels substantial but not overly heavy, it’s likely white gold.
Key Takeaways on White Gold
What is White Gold? White gold is an alloy of yellow gold mixed with white metals like palladium, platinum, silver, or nickel to give it a bright, silvery-white color.
Rhodium Plating: White gold is typically plated with rhodium to give it a reflective, white finish. This plating wears off over time and needs to be redone to maintain the appearance.
Karat Levels: The amount of gold in white gold is measured in karats, with common options being 18K, 14K, and 9K. Higher karat levels contain more gold but are also softer.
Pros and Cons: White gold offers an elegant and affordable alternative to platinum, but it requires maintenance and can cause allergic reactions in people sensitive to nickel.
Maintenance: Regular re-plating is necessary to keep white gold looking its best, especially if worn frequently.
White gold offers a beautiful and versatile option for those looking for durable, luxurious jewelry that won’t break the bank. Whether you're interested in an engagement ring or a timeless necklace, understanding the ins and outs of white gold can help you make an informed decision.
