Found silver necklace with blue sea-glass pendant

I found a necklace this afternoon around 2:15pm outside Riverside Market on Harbor Way, Eastern Shore. It’s an 18-inch sterling silver chain with a teardrop blue sea-glass pendant, and a tiny wave engraving on the edge. The back has a subtle initials stamp—looks like “AJ”—and the glass has a faint salt-stain patina from being near the water. The chain and clasp are in good condition, not bent, and the pendant is securely attached. If this could be yours, tell me the initials and approximate chain length to confirm, and we can meet up near the market to hand it over.
