Made of sterling silver and is plated with rhodium. Silver can tarnish (just like real silverware) so we have had it plated with Rhodium to ensure it's luster. Rhodium is a precious metal, more precious than gold because there is less of it in the world. It is also hypoalergenic to your skin and does not turn it green. It comes with an 18 inch rolo chain with the sought after lobster clasp.
