These Beautiful 2.33 carat simulated Sapphire Pendant is Rhodium Plated. The Gem Measures approximately 9mm by 9mm. The chain measures 32cm and is adjustable to 36cm, and has a spring clasp. And comes with a product care certificate. (What is Rhodium, Rhodium is a very precious metal that can cost ten times as much as gold or more! Rhodium is fabulous as a plating for jewellery because it is glitteringly, dazzlingly, white and mirror-like, but much whiter, and one of the most reflective of precious metals. Nothing sets off Gem Stones like rhodium plating does).
