Where can I buy a chain like this?

[Embo]

Hi everyone,

My sister has put an order in for a necklace like you see in the photo. I emailed Cooksons to see if they sold a chain like this which is sort of paper clip shaped, but they just replied to say they don't. Are there any other good chain wholesalers you would recommend?

While I'm on, can I also ask about the pearl? I've never set a pearl or any sort of bead before, so do I just order a half drilled pearl and then glue it onto some sort of finding? It a general jewellery epoxy glue OK?

Thank you as always
