What and Why Rhodium Plated


Why is TuaMea’s jewellery Rhodium Plated?

Rhodium plated jewellery adds an extra layer of protection to jewellery and produces a brighter white than sterling silver, white gold, or platinum. Realistically, jewelry cannot be crafted from solid rhodium because, despite its strength, rhodium is brittle. A layer of rhodium plating must be just the right thickness to keep it from cracking–.75-1.0 microns is perfect. Any thinner and the metal underneath would show; any thicker and the coating would crack. That perfect layer of rhodium can enhance the appearance, quality, and longevity of your jewelry.

Rhodium is non-toxic and completely safe. It’s the recommended option for sensitive skin, babies, and new piercings. 

Rhodium is also corrosion-resistant and does not rust. Because rhodium is strong, it does not need to be alloyed with other metals as copper that, over time, will corrode and leave behind dark green marks on your skin.

What is Rhodium Plated Sterling Silver?

Rhodium plated silver is sterling silver coated in rhodium to make it whiter and brighter. Silver is a softer metal, so rhodium protects it from scratches or wear. Solid silver is too soft to be fashioned into jewellery, so it contains 92.5% silver and 7.5% of other metals like copper. The traces of copper in sterling silver cause tarnishing. Adding rhodium plating prevents this from happening.

Rhodium versus silver

Silver is not as white or reflective as rhodium. It is softer and must be combined with other metals that make it susceptible to tarnishing. Sterling silver is often a base metal for rhodium since it is sturdy and high-quality. Rhodium adds some value and imperishability to silver.

Rhodium plated is based on preference. But luckily, you’re not forced to choose. Rhodium plated and sterling silver jewellery work best together. When coated in a layer of rhodium, silver becomes a better metal.
