Rose gold ring with ruby centerpiece and initials

Lost my rose gold ring yesterday around 3pm near the Meriam Library on the Chico State campus, right by the Main Street crosswalk. It's a 14k ring with a small marquise ruby center, and it has delicate leaf engravings along the band. Inside the band, the initials 'P.P.' are engraved, and there’s a tiny scratch from a bracelet snag. It was a gift from my grandmother and has huge sentimental value—I'd really love to get it back. If you found it, please reach out; I’m hoping to recover it soon.
