Silver ring with emerald-like stone found near Syntagma

I found a silver ring this morning around 7:30am outside the National Gardens Gate near Syntagma Square in Athens. It's a sterling silver band with a small emerald-like stone, about a size 7, and a delicate leaf pattern along the edge. On the inside there’s a tiny heart engraving and a 925 stamp, plus a faint dent from wear. If this sounds like yours, I’d love to help reunite you with it.
