The look of white gold at a silver price! This sterling silver humming bird pin perfectly mimics white gold and diamonds with its rhodium finish and white, red, yellow, and blue cubic-zirconia stones. The pin has a slide bail so it can also double as a pendant. Rhodium is a metal that is part of the platinum family. High-end silver and gold are rhodium treated to prevent oxidation and to have the white shiny look associated with platinum and white gold. This pin's rhodium finish will prevent it from tarnishing.
