Silver ring with light-blue gemstone

I lost my silver ring yesterday around 3pm near the Lakeland Public Library on Main Street. It's a size 6 sterling silver band with a round light-blue gemstone, surrounded by tiny marcasite stones, and it's an unbranded ring with a faint inner engraving that reads 'Hope'. The ring is a bit worn with small scratches but otherwise in good condition. It means a lot to me because it was a gift from my grandmother, and it carries sentimental value—I’d really appreciate getting it back if someone found it.
