Lost & found rings in Denver

Silver ring with sapphire, lost near Union Station

I lost my silver ring with a tiny sapphire set in a delicate halo yesterday around 3pm. It's an unbranded sterling silver ring, roughly a size 6, with a small scratch along the band and a faint engraving on the inside reading 'P.P.' plus a tiny heart. I was walking from the 16th Street Mall toward Union Station, and I must have taken it off somewhere near the corner of 17th Street and Wynkoop in LoDo. It was a keepsake from my grandmother, so it means a lot to me and I really need it back. If you found it, could you drop me a note or DM me? I'd be forever grateful.
