Rhodium plating is an antioxidative surface treatment - silver turns black and loses its luster when exposed to air. Silver rhodium plating is a technological procedure (plating) that serves to protect silver from blackening, yellowing and loss of luster. Because this treatment is nickel, it is also suitable for allergy sufferers.

This technique is also used for plating gold - this is how white gold is created. Since rhodium is one of the most expensive metals, the resulting price of silver jewelry is higher than that of ordinary silver jewelry without rhodium protection.
