Silver Ring from Estate Sale - Help with Identification

[RustyRelicHunter]

I purchased this ring along with a lot of other items at an estate sale. It appears to be silver, but it is not marked. The construction is rustic and the stone light blue with some pitting (it does not look like turquoise). Any suggestions on style, construction or stone? Thanks for any help you can give.

Looks like a handmade piece to me, maybe even Native American but without any marks it might be hard to prove. Cool ring! I hope it is silver.

It looks like it could be silver and worth about 5 bucks. Maybe a little more to the right buyer.

The construction of this ring looks a little cheap.

Still a nice ring.
