Hello all,
I am working on an adjustable lariat necklace project but I cannot find the piece that i need to make the necklace adjustable anywhere. Below are two examples of what I am trying to make. The center bar on the first necklace slides up and down to get the necklace on and off and to make it tighter or looser. That mechanism that allows the bar to slide up and down the chain is what I cannot find anywhere. The main difference on mine will be that instead of a bar there will be a 2 crt round brilliant that slides up and down. Please help if you know what this peice is called or where I can get one of these slide mechanisms.

on this one the diamond pave 'x' slides up and down the chain
