Rough surfaces outside in the deeper sections is allways no good sign.
Silver has no corosion.
As always good pics are maybe the key, but from this pics i don`t like this ring.

I made more pictures for you.

Oh yes, pics are sometimes the key.
From this pics the ring looks much better for me.
Still not good enaugh but i know its very hard to take good pics of this small items.
In the moment i can`t spot real faults, so i am more in the "like it gang" now.
