We have a woman's chain belt in gold tone metal with rhinestones on the round rings.  It was purchased with a lot of vintage items but I don't think this is all that old - I would place it at somepoint between the 1990's - 2010.  It measures about 42" from one end to the other with a pinch clasp on one end which fastens in at any point on the opposing end.    The finial on the belt is a 3/8" rhinestone.  The decorative portion of the belt with the rounds is about 15 1/4" with the remainder 25" being gold tone metal chain to link into.  The widest point on the belt is about 2 3/8" in w across the largest round.  It is very adjustable to fit almost anyone.  It is in good condition.
