Silver ring with sapphire and initials engraving

I lost my silver ring yesterday around 3pm on the ISU Normal campus, near the Bone Student Center by the grassy quad off Cardinal Court. It's a sterling silver ring, about 6 mm wide, with a small blue sapphire set in a bezel and a tiny crescent moon engraving on the outside. Inside the band, the initials 'A.P.' are lightly etched. This ring was a gift from my grandmother and means a lot to me, so I'm really hoping someone picked it up. If you found it, please let me know—I'll swing by the ISU Police or meet at the campus library to pick it up as soon as possible.
