I wish I could help you, because I have the same problem! My ring size is 12! 12! It's ridiculous- but I carry most of my weight in my arms and that goes all the way down to my finger tips. I sometimes buy thumb rings, but they often are only a size 10 (which actually fits my thumb, which is smaller than my fingers!).

I buy rings that look dainty on my hands- I really have to try them on because what looks chunky in the case can look dainty on my paws.

Have you looked online? You can get anything made in special sizes.

I don't know anything about silver except for the fact that I'm allergic to it but have you checked out Titanium jewelry? It's more in line with silver pricing and can come in some neat styles. Have you looked through the Stuller or Ingwer catalogs? They're big jewelry companies but I'm not sure if they deal in silver.

You can have rings sized. Speak to a reputable jewler about how much they can go up.

I can help you out here!

Peora has affordable jewelry and they have a plus size ring department with sizes between 9-13! Yes! 13!

Here is Size 12..the links to other sizes is on your left hand side.

They also have a site where you can get jewelry for free..just a $5.99 s/h charge. The stuff is constantly changing every 10-15 mins or so and plus sized rings turn up there too.

And all their stuff is silver.

Good luck!
