I suspect that this Ring likely dates to the second half of the last century and is in good overall condition as can be seen from the photos that form part of the description. The ring was tested as silver by the Auction house that this was bought from and I would say it fits a size K to L. The Ring has a gross weight of 7.2 grams. Dispatched with Royal mail. Returns will only be accepted for damage in transit only and not for any other reason such as change of mind fit et cetera.
