The chain, which is manufactured in Italy, is 925% Sterling Silver. The chain won’t irritate the skin or pull on the hair due to its round shape. It is flexible and extrememly difficult to break. The chain is treated with rhodium plate and will not tarnish. A special feature of the 22” chain is its ability to adjust the length to the wearer’s measurements. Because the clasps on the chains are easy to open and close, they are very well suited to people who have vision problems or who suffer from arthritis.
