Rhodium is a precious metal that is in the family of platinum. For rhodium plated jewelry, it involves plating the jewelry with a surface that guards against scratches that also gives a reflective white appearance. It increases shine, luster, and durability. Additionally, it will make your jewelry more resistant to scratches, and if it's silver, less prone to tarnishing. Another popular benefit to rhodium plating is the fact that it makes your jewelry hypoallergenic. This is because it's nickel-free. So if you have a nickel allergy, rhodium plating is a good option for you.
