Set of 2 Marcasite rings size almost 7, 1 is dome shape, other traingle shape

These are two marcasite sterling silver rings. They both say 925 on the band part. One of the rings has a domed shape and the other is a different triangle shape of one side bigger than the other. They are really pretty. On the ring size checker it has them as with three triangles almost size 7 ring size. The other ring has two different sides that are different sizes. One has 5 lines and then the other is three lines. They both have marcasite to decorate them, they are really pretty, they are sparkling they seem to be 6 and 1/2 inch and not a true 7 inch. I can not find any stones missing on the rings. But check the pictures to as the pictures are part of the description. I have more on sale and I will combine items to same shipping costs.
