Gold dragonfly necklace lost in Catskills

I lost my gold dragonfly pendant necklace yesterday around 3pm near the Phoenicia Diner on Main Street in Phoenicia, Catskills. It's an 18-inch gold-plated chain with a tiny dragonfly charm, and there’s a small emerald stone in the dragonfly's tail; the back is engraved with AK. It has sentimental value—it's a gift from my grandma and I really need it back. If anyone found it, please get in touch; I’d be so grateful to be reunited with it.
