Gold pendant necklace with moon charm

I lost my gold pendant necklace yesterday around 3pm near the Columbia Point Marina Park in Richland after grabbing a coffee at the café there. It's a slender 14k gold chain, about 18 inches, with a tiny round moon pendant that catches the light. The back of the pendant has the initials 'LM' engraved, and there's a small scratch on the front from daily wear. It means a lot to me—it's a gift from my grandmother and carries a lot of sentimental value. If anyone found it, I’d really appreciate knowing where it is so I can pick it up nearby.
