.925 Sterling Silver Ring Size 7

This is quite a pretty ring with, what I think is referred to as a moonstone? It has been years since I wore the ring and decided to sell it. I went over it with a silver polishing cloth, but it could use a much more thorough cleaning. I am not a jewelry person, but the last time I tried a ring on, it was a size 7. That is what I am going by as far as the size. I will be happy to answer any questions if I can.
