An item described as such comprises a core of 92.5% pure silver, alloyed with other metals, typically copper, to enhance its durability. This base metal is then coated with a thin layer of rhodium, a rare and precious metal from the platinum group. This outer layer provides a bright, reflective surface, similar in appearance to white gold or platinum. A ring crafted from silver and then finished with this plating exemplifies this type of jewelry.
The application of this outer layer significantly enhances the tarnish resistance of the underlying silver, mitigating the natural oxidation process that can dull its appearance over time. This results in a piece of jewelry that maintains its luster for a longer duration, requiring less frequent polishing. Historically, this plating process has provided a cost-effective method for achieving a high-end look with increased longevity compared to untreated silver.
