Mystery Chains

Hey all,

Long time lurker, finally decided to register and see whether the community can help ID a couple of pieces I've been struggling with for a long time. Has anyone come across the following?



Both are on chains / necklaces. I'm aware the second one is quite difficult to read so let me know if another photo is required.

Thanks in advance for any help.

 

AR and SW? Looks like.... The first one is probably sterling; the second one might be. Most of the time those tab thingies mean the chain is costume, but a few turn up in silver.

 

Thank you, I'll photograph these a bit more tonight and share to help with identification. They're murky gold colour so surprised if they are Sterling.

Wondering if anyone has seen the AR mark before.
