Gold ring with sapphire, engraved initials inside

I lost my gold ring yesterday around 3pm outside the Buffalo Bill Center of the West in Cody, Wyoming, near the sculpture garden. It's a 14k yellow-gold solitaire with a small sapphire centerpiece about 6mm wide, and the band is slender with a subtle notch by the setting. Inside the band there’s an engraving 'A.K.' and a tiny scratch that happened long ago. The ring has serious sentimental value—it was my grandmother’s ring, passed down to me, and I really need it back. If someone found it, please get in touch; I’d be incredibly grateful and heartbroken if it was lost forever.
