Stainless steel, has not tarnished and chain is beautifulWith stainless steel, you don't have to be concerned about tarnishing or turning your skin green. It is a delicate necklace not to be worn in the shower or swimming! The latch is a tad difficult to master. Could be improved upon. Overall, everyone I gifted them to liked them very much. Sorry to see that they are no longer available.Easily brokenDainty yet well made and beautifulGreat priceOnly wore it for -1- day and broke. It tarnished and smells horrible.Really waited for necklace, so sorry it was not worth the purchase
