This ring is in Like New Condition without Tags - Never Worn since being professionally polished. Ring comes with a COA. The ring band measures 17mm wide along the face. Note: The hallmark is small and hard to see especially if held up to the light because is it so shiny from just being polished. I recommend placing the ring flat on a solid table and sit in a chair to view the inside of the ring while keeping it on the table to avoid the glare.
You might have to flip the ring over to check both edges. A magnifying glass will also work. Pictures provided of the hallmark to assist in identifying where it is located on the ring identified in the listing.
