Help Me Too!

I'm following Ms. Mary Jane and asking the hive for help. I need a necklace. I don't have any idea except that I want it to kind of match my grandmother's earrings. I did have a plan at one time. I was going to take the matching ring and have the stone part turned into a pendant. Then I was going to have the band part formed into a complete circle and have it used as a pendant for a necklace for my sister. That way we both got a piece of the heirloom. But the ring is M.I.A. No one knows where it is. So I have to come up with something else and I stuck. I have a gold chain I can wear if I find a pendant. I just need the pendant part or a new necklace all together. Suggestions? Links?
