White gold isn’t a naturally occurring metal like yellow gold. Instead, it’s an alloy, meaning it’s a mixture of pure gold with other metals. The primary purpose of these added metals is to create a white or silvery appearance while enhancing the gold’s durability. The specific metals used in white gold alloys, and their proportions, can vary, but here’s a breakdown of the typical composition:
The foundation of white gold is pure gold, which is measured in karats. Pure gold, or 24 karat gold, is 100% gold. Since pure gold is very soft and malleable, it’s almost always alloyed with other metals to improve its hardness and suitability for jewelry. In the case of white gold, the goal is to lighten the yellow hue of pure gold and make it more durable.
The most common additions to create white gold include:
- Nickel: For many years, nickel was a primary metal used to achieve a white appearance. However, nickel is known to cause allergic reactions in some individuals, leading to skin sensitivity and irritation.
- Zinc: This metal is often added along with nickel to further enhance the alloy’s hardness and color.
- Silver: Silver is sometimes used in white gold alloys, helping to lighten the color.
- Palladium: As a hypoallergenic alternative to nickel, palladium is increasingly popular in white gold alloys. It not only whitens the gold but also adds to its durability, making it a preferred choice for those with sensitive skin. It tends to be more expensive than alloys with nickel.
- Copper: Some recipes include copper to modify color and malleability.
The proportion of pure gold dictates the karat value of the white gold. For instance, 18k white gold is made up of 75% pure gold and 25% other metals, while 14k white gold comprises 58% pure gold and 42% alloys. The remaining portion of the alloy is the mix of metals listed above.
Additionally, most white gold jewelry is rhodium-plated. Rhodium is a very hard, silvery-white metal in the platinum family that is applied as a very thin coating on the white gold surface. This plating gives the jewelry its bright white luster, enhances its durability and makes it more resistant to scratches. However, rhodium plating wears off over time and will require re-plating to maintain its original look.
Frequently Asked Questions (FAQs) about White Gold
1. What is the Point of White Gold?
White gold has become very popular due to its aesthetic appeal, as it enhances the brilliance of diamonds by not reflecting colour through the stone. It offers a modern, silver-colored metal look that appeals to those who prefer it. White gold allows wearers to embrace a sleek, contemporary look while still enjoying the prestige and value of gold.
2. Is White Gold Better Than Silver?
White gold is generally considered superior to silver in terms of durability and strength. Silver, in its pure form, is quite soft and prone to scratches and tarnishing. White gold, due to its alloy composition, is much more robust. Furthermore, white gold’s rhodium plating also adds to its durability and tarnish resistance, whereas silver is prone to tarnishing unless regularly polished.
3. Which is Better: Yellow Gold or White Gold?
Both white and yellow gold have their advantages and disadvantages. Yellow gold is typically softer and more prone to scratches and dents, making it the less durable of the two. It requires frequent polishing to maintain its shine. White gold, on the other hand, is more resistant to wear and tear, especially when rhodium-plated. The choice between the two often boils down to personal preference, style, and the intended use of the jewelry.
4. Which is More Classy: White Gold or Yellow Gold?
The perceived class of white and yellow gold is subjective and often a matter of personal taste. Yellow gold may be favored by those with a romantic or vintage leaning, while those who prefer a modern, sophisticated style may prefer white gold. Ultimately, the “classiest” choice is the one that resonates most with the wearer’s individual style and personality.
5. Do Diamonds Look Better in White or Yellow Gold?
High-grade, colorless diamonds tend to look more stunning in white gold or platinum settings. The white metal enhances the diamond’s brilliance and allows its color to truly shine. A yellow gold setting can reflect a yellow tint back into the diamond, potentially diminishing the brilliance of a high-quality, colorless diamond.
6. Should I get 14K or 18K White Gold?
While 18K white gold is available for those who desire it, 14K white gold is often recommended. It’s more affordable and has a higher percentage of alloys, making it whiter, harder and more durable than 18k. The added alloys in 14k white gold make it more resistant to wear and tear, making it ideal for daily wear, particularly for rings.
7. Can you shower with White Gold Jewelry?
While solid white gold won’t be harmed by showering, it is generally not recommended to shower with your jewelry. The chemicals in soaps and shampoos can dull the shine of your white gold and also cause the rhodium plating to wear off sooner. Additionally, showering with gold-plated jewelry can cause the gold layer to eventually wear off, so it is best to avoid this entirely.
8. What does 925 Mean on Jewelry?
The number 925 stamped on jewelry indicates that it is 92.5% silver and 7.5% of another metal, typically copper. This marking, known as a “hallmark,” signifies high-quality sterling silver. It is not a marking found on white gold, which uses a different set of markers (like 14K, 18K, etc.).
9. Why Avoid White Gold?
Although widely popular, white gold is not without its disadvantages. One point of concern is that it is less durable than metals like platinum, because it is softer. Any scratch to the surface removes a tiny amount of gold. Because of rhodium plating, white gold also requires maintenance, as the plating wears off over time and needs to be reapplied periodically.
10. Which is Better: Platinum or White Gold?
Platinum is generally considered more durable and heavier than white gold due to its higher density. This density makes it a highly desirable option for engagement rings and other items subject to significant wear. While more expensive, it is less likely to require the regular rhodium plating needed by white gold to maintain its bright white appearance.
11. What not to do with White Gold Jewelry?
Avoid exposing white gold jewelry to strong chemicals, abrasives, and harsh cleaners, as these can damage the rhodium plating and potentially loosen gemstones. Be sure to remove your white gold during activities that may expose the metals to harsh chemicals. Deep cleaning should be done professionally.
12. How Can You Tell Real White Gold From Fake?
Several simple methods can help you identify real white gold:
- Tarnish Resistance: Real white gold does not tarnish due to its rhodium coating.
- Platinum Comparison: Platinum is significantly shinier and harder than white gold.
- Carat Stamp: Genuine white gold will have a carat stamp, such as 14K or 18K.
- Scratch Test: Scratching it on an inconspicuous area may show if it is plated with another material.
13. Is There 24K White Gold?
There is no such thing as 24K white gold. Pure gold is naturally yellow, and the white color is achieved through alloying with other metals. Any white gold jewelry will be below 24 karat, with the balance of the alloy being made up of other metals. For example, 14k white gold would be 14 parts gold and 10 parts other metals.
14. Why is White Gold More Expensive?
White gold jewelry can be slightly more expensive than yellow gold jewelry even if they have the same karat value because the additional manufacturing processes are more complex. White gold requires mixing with other metals to achieve its color and is often coated with rhodium, adding to the production cost.
15. Why is My White Gold Turning Yellow?
A yellowish tint in your white gold jewelry indicates that the rhodium plating is wearing off, revealing the natural yellowish tint of the gold alloy beneath. This is not a sign of poor quality. The rhodium layer is very thin and will eventually need to be reapplied to restore the bright white color. Rhodium plating is part of normal maintenance for white gold jewelry.
By understanding the composition of white gold and its unique properties, individuals can make informed decisions when buying or caring for their white gold jewelry. Its combination of beauty, durability, and versatility makes it a popular choice for a wide range of jewelry styles.
