Unusual ring

[SkyPirate]

Has anyone ever seen a ring like this? It says Sterling on the inside at the bend. I have never seen a design like this and was wondering what the age may be.

Perhaps the design is not so unusual - I think the ridges at the top of the ring are stone settings which are clearly not there anymore.

I guess that is possible. This was found where a very old house once stood, I found an 1891 IH cent within a few feet of this ring, however the IH was a lot deeper. Thanks.
