I bought this quite a while ago and wore it a few times before putting it away. The pendant top measures approximately 1 cm for the upper part and 3.5 cm for the cross, including the clasp. The chain is approximately 50 cm long. I've polished it because it was tarnished, but since I'm not a professional, please check the condition in the photos. The stone set in it is a dark navy blue. I don't remember the details, such as what kind of stone it is. The only included accessory is the bag. This is an old item that has been stored by a private individual. Thank you for your understanding.
