This is an unusual item. It is a pretty heavy base metal chain with a silver tone plating. It seems like a pretty rugged good quality chain. It has a lobster clasp on one end, and a large 13mm ring on the other end. The links of the chain measure 7x5mm. The length of the chain is only 13 inches which is small. It looks great on a slender girl here at the office but it will not fit a mans neck. I think this might be used in a number of ways, not only as a necklace. Someone with thin wrists could double this as a bracelet. Also the length is very easy to adjust. The lobster clasp will clip right on to any of the links so this could be used as an anklet or single wrap bracelet simply by clipping it where it fits. You could size this to particular customers and just clip off the extra.....or move the large ring down if you want. How about a necklace extender? Seems like a number of possible uses for this chain.
