Silver ring with emerald centerpiece found on Lincoln Road

I found a silver ring this afternoon around 2:15 pm wandering along Lincoln Road in Miami Beach, not far from the Shake Shack. It's a medium-width sterling silver band with a small oval emerald that looks a bit worn but still shows its color. The setting has a delicate milgrain edge, and inside the band there's a tiny engraving that reads 'AJ' with a small crown motif right above it. The ring is in good condition overall, just a few surface scratches from daily wear. It feels sentimental and I'd love to see it back with the owner—if you know who it belongs to, I hope this helps.
