Silver-tone necklace with teal teardrop pendant

I found a silver-tone necklace this afternoon around 2:15pm along the Lake Eola Park promenade on East Central Boulevard in Orlando, near the fountain. It’s a delicate 18-inch chain with a teardrop pendant that holds a teal-blue crystal. The back of the pendant has a tiny engraving 'A.J.' and the lobster clasp shows no obvious brand stamping. The chain has a bit of wear and the pendant has a small scratch along the edge, but it still looks pretty. It feels like something someone wore for a special moment, and I really hope to reconnect it with its owner.
