Gold ring with emerald centerpiece, sentimental heirloom

I lost my gold ring yesterday around 3pm near the Sundial Bridge in Turtle Bay. It's a size 7, 18k yellow gold ring with a small emerald set in the center and tiny diamond accents along the shoulders. There's a faint inscription inside the band: 'M.J. 1998'. The ring is slightly worn, with a tiny scratch on the inner edge, but it's still precious to me because it was my grandmother's. If anyone picked it up, I’d be forever grateful to get it back; it has real sentimental value. Please contact me if you found it near the river trail between the Sundial Bridge and Turtle Bay Exploration Park in Redding.
