FREE: 5 rings one says sterling

The listing, 5 rings one says sterling has ended.

You are bidding on 5 rings i found in my moms jewelry box. she died two years ago at age 87. I was trying to see if any were marked but my eyes arent that great even with glasses. I got out a magnifying glass and this is what i can tell you.
The one with the turquoise color stone the band looks tarnished and says something with the word sterling.next is s amall golden band probably only like a size 5 n, no markings.
Next is another gold tone ring it does have something engraved in the band but I cant read it.
next is a silvery band with a rhinestone or cubic zirconia stone.this looks like its never been worn. I thnk most of these rings run around size 7 or 8 except the one small one I mentioned..Last is another ring this one has engraved inside It either says MN5 or MNS. it has red stones in the middle One is missing.two little circles around it . i really know nothing else about this stuff.Sold as is as I really dont know anything about them and tried to describe them as best as I could. I do not refund credits if you change your mind.
