This is a supper nice combo of pendant & chain. They will be sold separate or for a little discount both pieces. The rope chain is 18" & weighs  20.8 oz. The heart pendant with the beautiful elongated bail is 15.6 grams. I would hate to separate since they look so good together but will. The pendant is marked Mexico & 925. It measures 1 1/16' across the bail. The heart is around 1". It really is stunning.
