I don't know what you girls are looking for, but I looked around and found some stuff. I've posted a few things below, but if you want to give me some parameters, I would love to look around for something for you two...
Thank you so much Drew!! I really like two of the lockets from the first link. Of course, I picked the most expensive ones on the page, whoops! Now I just have to find a 20 inch chain and make up my mind. I like these two because the shapes are a little funky.
n/s if you want a real gold chain or would settle for a substitute, but there's a place on 37th and 6th that sells fake chains by the inch. it's one of those trim places, but i got a heavy gold chain from there that looks really nice and hasn't turned at all.
