Featured 3 Silver Rings

Hi Everyone,
I don’t have high hopes, but these were inexpensive.

One has sea life on it. That is the only one that seems marked. I can’t manage a photo, but I think it’s 925.
Is it a souvenir or maybe cigar band?

One has stones or faux stones and looks to have been sized.

The last one has a hollow design of circles.

Any thoughts? Good or Bad is fine.

Thank you for looking!

 

Oh, thank you I did not know that.

 

I did find this, but it’s a broken link. I think this is a souvenir like those turtle rings. Hawaii or such.

 

I think the one with glass/stone has wood, does that make sense?

 

Thank you, Kiko!

 

I found a 925 on the hollow stamped ring.

I will take more photos in the daylight tomorrow of the inlaid one. The inlaid part is all brown, except the center stone. I can see some pores in the center stone through a loupe. For now here’s some since I’ve cleaned it. The brown seems discolored toward the center stone ( maybe glue?)

 

They came together. I saw the Koa wood ones too, maybe it’s along those lines.

 

I must have bad sensory perception.
It’s difficult to tell, but I think the blue/green is cold and the brown is warm. Wood was just what first came to mind, but I don’t think the brown is stone.

 

Horn would be very possible, I’ll look into that. Thank you for the link.
It’s unusual, I’ve gotten my money’s worth already from researching them.
It’s a bit bleak out, Will try later for better photos.
