Two-tone ruby ring lost on Bay Road

I lost my two-tone ring yesterday around 3pm. It's a size 6, yellow gold-plated ring with a slim white-gold bezel and a tiny square-cut ruby in the center. There's a delicate 'JL' engraving on the inner band and a faint micro-scratch along the outside edge; there's no obvious brand marking. I think it slipped off while I was at the Meijer on Tittabawassee Road in Saginaw, near the checkout line. This ring was a gift from my grandmother and means a lot to me; I’d be incredibly grateful to have it back if anyone finds it.
