Silver ring with blue sapphire and engraving

I found a silver ring with a blue sapphire set in a clean bezel, plus a delicate fern engraving along the outside. It looks like sterling silver, about a size 6.5, with a few light scratches from wear. I found it this afternoon around 3:15 pm near the Memorial Union steps on the OSU campus in Corvallis. The inner band is stamped '925' and there are two tiny leaf engravings on the outer edge—the sapphire catches sunlight beautifully. I’d really like to help reunite it with its owner; if it sounds like yours, we can figure out a safe handoff here in Corvallis/Albany.
