Lost sentimental silver ring with bright green emerald near Myriad Botanical Gardens, Oklahoma City.

I lost my sentimental silver ring with a bright green emerald while out walking my dog near the Myriad Botanical Gardens in downtown Oklahoma City. It must have slipped off my finger because I often take it off while washing my hands. I've had it for years, and it means so much to me. If anyone finds it, please let me know!
