Silver sapphire ring with PP engraving

I lost my silver ring yesterday around 3pm near the ASU Student Union on Howard Street in Boone. It's a slim 6mm silver band with a bezel-set sapphire about 4mm across, and on the outside edge there's a tiny crescent moon with 'PP' engraved inside. It has a lot of sentimental value—it's a gift from my mom and I’ve worn it almost every day since college. I remember adjusting my backpack strap and realizing it was gone; if anyone found it, please reach out, I’m really hoping to get it back.
