In the jewelry sector, the search for a balance between durability and aesthetic perfection is constant.
Although precious metals like gold or silver have been used for millennia and remain fundamental in crafting all kinds of pieces, they can also benefit from other materials to further enhance their beauty and resistance. This is where a discreet yet effective ally comes into play: rhodium. Discover with VIDAL & VIDAL what it is and why it’s used in fine jewelry.
What is rhodium plating?
Rhodium is a metal from the platinum family that gives jewelry an extremely bright finish while providing superior protection. It’s a rare and valuable material that has become a quality standard within this industry.
Specifically, rhodium plating is an electroplating process known as rhodium plating in which a thin layer of this material is deposited onto a piece made of another metal, especially gold, silver, or platinum. The reason it’s widely used in jewelry is its high resistance to tarnishing and corrosion, in addition to the fact that technology now allows for controlled and accessible application.
Why is rhodium plating used in jewelry? Advantages
The main reason to use rhodium plating is the combination of aesthetics and functionality. In the case of white gold, for example, it’s applied as a final layer to achieve that characteristic intense, luminous tone, which also enhances the sparkle of diamonds and other set gemstones.
On silver, rhodium plating offers an elegant solution to its natural tendency to tarnish. Contact with oxygen in the air and humidity causes it to darken over time, producing the well-known patina. During this process, the rhodium layer acts as a protective shield that prevents this chemical reaction, helping jewelry retain its original shine for longer.
Besides improving color and preventing oxidation, rhodium adds significant hardness to the surface of pieces. It provides superior resistance to abrasions and scratches from daily wear, which is especially useful for frequently worn jewelry such as wedding bands or solitaires that are constantly exposed to potential damage.
Another key benefit, which is becoming increasingly relevant, is its hypoallergenic nature. Some people experience reactions to certain metals present in traditional alloys, such as nickel. By coating pieces with rhodium plating, an inert barrier is created between the skin and the base metal, minimizing the risk of irritation and allowing those with sensitive skin to enjoy their collection comfortably.
Care for rhodium-plated jewelry
Despite its many advantages, it’s important to know that rhodium plating is not permanent, since it will wear down over time and with use, especially in areas of greater friction. The lifespan of the layer largely depends on its thickness, the type of jewelry, and the wearer’s lifestyle. A ring, for example, will show signs of wear before earrings or a pendant.
When the color of white gold starts to show through or silver begins to darken, it’s time to apply a new rhodium plating. This is a relatively common and affordable maintenance service offered by many experienced jewelers. In any case, to prolong its useful life, it’s advisable to follow some simple care guidelines:
- Avoid contact with harsh chemicals such as chlorine, perfumes, hairsprays, or cleaning products.
- Remove rhodium-plated pieces before showering, doing household chores, or engaging in intense physical activity.
- Use lukewarm water, neutral-pH soap, and a soft cloth for cleaning.
Without a doubt, rhodium plating represents the perfect balance between the timeless beauty of precious metals and technological innovation. It’s a functional treatment that significantly improves the aesthetics and durability of your most valuable jewelry. It provides solid protection against wear as well as a hypoallergenic solution. It also ensures that pieces not only shine at the moment of purchase, but endure over time with proper care.
