The listing, Golden Horse Charm has ended.
This necklace has a very small chain, like for a child. I think it is 13-14" maybe a bit smaller. I am not sure of the metal. The only problem with the necklace is that the clasp sometimes gets stuck open. You have to push the lever back to closed position physically to make it close instead of it popping closed on its own. But when it is closed it stays that way till you open it. There is beautiful detailing on the horse charm.
