Hi there and welcome to my shop! This is a transparent pendant made from resin. It has tiny fluffy clouds on a bed of iridescent flakes reflecting the light behind them. The necklace chain, as well as the finishing clasp and findings are all made of stainless steel. Stainless steel is known for its resistance to tarnishing, rusting, or discoloration. The necklace length is 18” with a 2" adjustable extension chain so it can be worn at a desired length, finished with a lobster clasp. If you have any questions about this item or any other item, please do not hesitate to reach out. Thank you for visiting my shop!
