14k gold ring with emerald and initials

I lost my 14k gold ring yesterday around 3pm near The Northern Hotel on Main Street in Billings. It's a slim comfort-fit band with a small emerald set in a bezel and a faint scratch along the inner edge. Inside the band is engraved the initials 'P.A.' and a tiny date on the inner edge, a telling mark I always remembered. The ring is sentimental - it was my grandmother's, and I really need it back. If you found it, please reach out; I can describe more details and offer a small reward.
