Rhodium plating has gained massive popularity when it comes to jewellery because of its shine and anti-tarnish properties. Although beautiful, many people are uncertain of what rhodium plating means. Knowing what it is and what it does and does not do helps inform smarter purchasing. This blog is a comprehensive overview of everything you need to know about rhodium plating in a clear and informative way.
Defining Rhodium and Its Role in Jewellery
Rhodium is a rare silvery-white metal that is a member of the platinum family. It is extremely reflective, making it perfect for adding to the look of jewellery. Its corrosion and oxidation resistance make it more desirable. One issue is that rhodium is too scarce to be used as a solid normally. Instead, it is used as a plating on other metals.
A rhodium plate is an electroplating of rhodium. The process involves making a thin layer of rhodium on other metals. This is usually done for white gold, silver or platinum jewellery. The idea is to polish and protect the finish beneath. The plating also covers any yellowish hues in white gold. As a result, the jewellery looks brighter and more homogenous.
Rhodium layer thickness is typically 0.75 to 1.0 microns. The change to individual components might not seem like much, but when applied, it is enough to make a visual difference. A thicker plating can be more durable, though it may come at a higher price. Commercial jewellery nearly always uses off-the-shelf plating for cosmetic appearance and cost-effectiveness. So, the durability is dependent on how much wear and tear it gets.
It is not permanent. The plating wears off over time. How fast this happens depends on how the device is used and the exposure to chemicals. Other items, like rings that receive frequent contact, may show signs of wear much sooner. Use regularly to keep the finish in place. This is good to bear in mind when purchasing rhodium-plated jewellery, so expectations are managed.
The Plating Process Explained
Rhodium plating is a multistep process that helps achieve an even and durable finish. The jewellery piece is washed to get rid of excess dirt or oils. This removes anything that might inhibit adhesion of the rhodium layer. Ultrasonic machines or steam cleaning are typically employed for cleaning. The cleanliness directly influences the plating quality.
Once cleaned, the piece is dunked in an electro-cleaning solution. This process neutralises any remaining impurities. The object is then rinsed to eliminate any remaining solution. This initial phase is very important to prepare the surface. These allow rhodium to bond properly to the core metal.
The next process is to electroplate the jewellery in a rhodium solution. The item is submerged and an electric current is passed through the solution. This causes the rhodium particles to adhere to the metal. The item is submerged and rinsed again. This results in a stunning, high-shine finish.
And finally, the piece is dried and polished for presentation. Under magnification jewellers can view this item to ensure an even coat. More rhodium can be applied if needed. The whole process is relatively quick and usually done in less than an hour. But expertise is needed to achieve precision.
Benefits of Rhodium Plating
Jewellery looks a lot more attractive when it is rhodium-plated. It leaves a reflective, mirror-like finish that’s nearly impossible to beat. This lustrous surface makes for an even more elegant piece, even a simple one. The bright white luster is especially popular for engagement and wedding rings. It gives a luxurious, premium look.
One other important advantage is its resistance to tarnishing and corrosion. Metals like silver tend to discolour over time. Rhodium plating serves as a protective layer against such alterations. This helps jewellery to stay newer for longer. This minimized the amount of buffing needed.
Rhodium is hypoallergenic, meaning that it does not react to sensitive skin. Certain metals can be irritating, especially nickel. Rhodium coating significantly reduces these risks. This becomes a key consideration for pieces intended to be worn daily. Making rhodium-plated jewellery a more secure option for a lot of individuals.
The plating also gives a slick surface that resists hairline scratches. It’s not scratch-proof but does afford some level of protection. Helpful for rings and bracelets that touch hard surfaces often. Overall, the plating is functional and adds to the value, both appearance-wise and the aesthetic value.
Limitations and Maintenance
Although rhodium plating does offer many benefits, it has its limits. One of the biggest is its temporary nature. And the plating will wear off over time, particularly on high-contact pieces. That’s when replating becomes necessary to maintain the look.
Chemicals can speed the degradation of the rhodium layer. Household cleaners, chlorine and even lotions can harm the coating. Plated items should be removed before swimming or cleaning. Proper storage and occasional cleaning also extend the finish.
Frequent replating can become expensive. A replating session usually costs £30 to £60. While this seems small, it adds up to ongoing expenses for garments you wear regularly. Although certain jewellers provide free replating for a set time period. Consumers should look for these information at the time of purchasing.
Moreover, not every jewellery item can undergo rhodium plating. More elaborate pieces may not be as forgiving. Plus, items that are vintage or distressed may not survive the process well. Ask a professional jeweller whether it will work.
Common Use Cases in the Jewellery Industry
Rhodium plating is common across many types of jewellery. This treatment is most often applied to white gold pieces. That is because white gold tends to have a yellowish hue. Rhodium hides these tones for a whiter, brighter finish. That is now just standard in the industry.
Rhodium plate also has a good effect on silver jewellery. Silver oxidizes rapidly in air and moisture. This chemical reaction is prevented by rhodium coating. This means that silver pieces stay shiny longer. The plating also means less polishing is needed.
Platinum pieces might also be plated with rhodium for extra shine. Rhodium boosts the luster of the platinum, which is already durable. Some consumers like this extra brightness. Again, your preference in taste and style will be what decides. It offers a flexible appearance for various aesthetic styles.
Rhodium is also used in watches, cufflinks, and other accessories. These items get both the aesthetic and functional properties. That protective layer is particularly handy in wear-everyday items. This increases its durability and improves its overall aesthetics.
