Gold ring with emerald and KT initials

I lost my ring yesterday around 3pm near the River Park shopping center, outside the Starbucks on Shaw Ave in Fresno. It's a thin 14k yellow gold ring with a small emerald bezel-set, and the inner band is engraved with the initials KT. There's a faint wavy etching along the outer edge and a couple of tiny scratches from daily wear. This ring means a lot to me—it was a gift from my grandmother, and I’m really hoping to get it back.
