An item composed of 92.5% silver, alloyed with other metals for durability, is coated with a thin layer of rhodium. This coating, typically applied through electroplating, enhances the underlying metal’s properties. For example, a ring crafted from the specified silver alloy might receive this treatment to improve its resistance to tarnish.
This surface treatment provides several key advantages. It significantly increases the piece’s resistance to scratches and tarnish, maintaining its luster for an extended period. Furthermore, the coating imparts a brilliant, white appearance, similar to platinum or white gold, offering a luxurious aesthetic at a more accessible price point. Historically, such plating has been used to enhance the appearance and longevity of various metal items.
