STYLETHREAD -- LET'S TALK SHOP!

Okay so I have been in search of a yellow gold ROUND locket necklace. I've searched ebay and my local jewelry stores but haven't found the right one. I don't want it to be huge but also not so small that the only pic that would fit into it is my hubby's eye. Anyone know where I can get something like this or any suggestions? Thank you so much!
