Rhodium is a metal element that belongs to the same family as platinum. It is the 45th element in the periodic table and takes its name from the Greek word “Rhodon” because the element looks like a rose under the microscope. It is a very expensive metal, almost ten times as expensive as gold and very shiny. However, it is not used to make jewelry yourself as it is extremely brittle.
Rhodium is used to coat jewelry made of white gold, silver or platinum. Imitation rhodium plating is used to give the jewelry a shinier and stronger characteristic. Surprisingly, it offers protection against tarnishing and scratches, although it is itself brittle when used as a coating for metal jewelry. It also contributes to the quality and lifespan of the jewelry.
The rhodium plating is carried out by first thoroughly cleaning the rhodium plates with cleaning agents. Then the rhodium plates are immersed in a solution (electrolyte) that already contains the metal. The electrolyte or solution is kept at a temperature between 30 and 50 degrees Celsius. The other metal to be plated is also immersed in the solution and then low density electrical current is passed through the solution to complete the rhodium plating process.
The most common use of rhodium is probably the coating of white gold. This is because white gold made by mixing gold with silver, palladium, or nickel still has a yellowish tinge. To give it a really “white” and lighter sheen, rhodium is plated on it. The rhodium plating gives the slightly matt surface made of white gold shine and shine and extends the service life. However, the jewelry must be regularly coated with rhodium to maintain the shine. Rhodium plating is also used for silver jewelry because sterling silver is very soft and insensitive to scratches and damage. As soon as the jewelry is coated with rhodium, it becomes scratch-resistant and looks lighter and more polished.
Another advantage of rhodium is that it is hypoallergenic. Some people sometimes complain of an allergy to white gold, gold and silver and have to stay away from jewelry made from these metals to avoid skin allergies. A coating with rhodium completely solves this problem, and even people who are allergic to the main metal can happily flaunt their jewelry without the agonizing worry of developing allergies. If you are concerned about your allergic reactions to jewelry, you can simply rest with rhodium-plated jewelry.
Rhodium as a metal is therefore very useful for the jewelry industry. The imitation of rhodium gives jewelry pieces a more shiny and shiny appearance. It also helps strengthen the base metal used to make jewelry such as silver or white gold, and makes it scratch and damage resistant. Not only that, since it is naturally hypoallergenic, people who are allergic to various precious metals can also wear jewelry that they otherwise could not wear.
