This box style pendant chain can be worn by itself or with a charm. It is 20" long and measures 1.2mm wide all the way around. It has a secure spring ring clasp and soldered end caps. It is solid yellow gold and is stamped 14K Italy on the end caps and 585 (14K) on the clasp. I have cleaned it in the ultrasound and polished it. I don't see any kinks or marks in it. This chain is in very good condition. Solid gold, not plated and perfect for any age! Please feel free to contact me with any questions you may have prior to purchasing.
