18k gold plating is one of the most widely used techniques for embellishing jewelry pieces, providing the appearance of pure gold without the associated cost. However, many people wonder if 18k gold plating oxidizes or turns black. In this post, we’ll explain everything you need to know about this process, how to care for your jewelry, and what you can do to extend the life of your gold-plated pieces.
What is 18k gold plating?
Gold plating is a process in which a thin layer of gold is applied over a base metal using an electroplating technique, which uses an electrical charge to bond the gold to the base metal. This layer of gold is what gives plated jewelry its shiny, luxurious appearance. The most common metals used as bases for gold plating include:
-
925 sterling silver.
Widely used in fine jewelry, it provides a quality base that, even if worn by the plating, remains valuable and reusable.
-
Stainless steel.
It stands out for its strength and durability, which helps prolong the life of the gold plating.
-
Brass.
A more economical option, but less durable as it tends to darken or corrode over time if the gold coating wears off.
At Salvatore Plata, we primarily use 925 sterling silver and stainless steel as base metals, ensuring our pieces are strong, durable, and high-quality.
How karats influence the finish of gold plating
At Salvatore Plata, we strive to offer a variety of golden hues to suit different tastes and styles. To achieve this, we use different karats of gold in our plating, depending on the desired finish:
- 14k gold plating. Provides a lighter, softer golden tone, ideal for more understated pieces.
- 18k gold plating. It offers a more intense and warm golden finish, perfect for designs that want to stand out.
The choice of karatage is related exclusively to the aesthetics of the piece and does not affect its durability. Regardless of the type of gold used, we apply rigorous quality controls to ensure the gold plating remains uniform and shiny. We combine traditional jewelry techniques with cutting-edge technology, allowing us to create unique pieces with an impeccable finish.
Does 18k gold plating oxidize and turn black?
Pure gold (24k) does not oxidize, as it is a noble metal that does not react easily with oxygen or moisture. However, gold-plated jewelry may change its appearance due to several factors:
- Wear of the gold layer. Over time, constant rubbing can wear away the thin layer of gold, exposing the base metal.
- External factors. Chemicals such as perfumes, creams, soaps, or chlorine in pool water can affect the appearance of gold .
- Skin pH. Continued contact with the skin, especially if it has an acidic pH, can accelerate the deterioration of the gold plating.
- Humid climates. Prolonged exposure to humid environments can also affect gold-plated jewelry .
In some cases, if a gold-plated piece of jewelry darkens or turns black, it’s advisable to take it back to the place where it was purchased so the cause can be analyzed. This doesn’t mean the piece is of low quality; it could be due to a specific problem during the plating process or a reaction to external agents.
How to care for 18k gold plating
Proper care is key to maintaining the beauty and prolonging the life of your gold-plated jewelry. Below are some practical tips:
- Avoid exposing your jewelry to chemicals such as perfumes, hairsprays, creams, or detergents.
- Remove jewelry before showering, swimming, or exercising. Sweat and water can accelerate wear.
- Clean regularly with a soft cloth to remove any dust or grease.
- Store your jewelry individually in cases or bags to avoid scratches between pieces.
With this care, your jewelry will maintain its gold appearance for longer, looking like new.
What should I do when my gold-plated jewelry has turned black?
If you notice that your gold-plated jewelry has dulled or darkened, don’t worry; there’s a solution. In that case, we invite you to try the following:
- Cleaning your home. Use a soft, damp cloth with a drop of mild soap to gently clean the surface. Dry thoroughly afterwards.
- Renew the gold plating. If the gold coating is very worn, you can take your jewelry to a professional to have it replated and return the piece to its original state.
It’s important to remember that wear and tear is normal over time, but with proper maintenance you can significantly delay it.
