Sterling silver and moonstone ring..beautiful stone. Solid silver band design

I found this is in an old jewelry box of my moms..so many things to post! It’s a cool ring. It’s pretty big as u can see by pic on my small hand..I dont have a ring sizer but I swear a 71/2 and it fits my middle. If really interested and need exact measurements I will get it professionally sized. It has been worn and in light I can see a few scratches in the silver but nothing that detracts from it’s over all beauty. The stone in perfect shape no scratches or cracks. This is my first post..I have a mercari site with 100% feedback. If I can answer any questions don’t hesitate to message. Thnx and be well
