Emerald green satin gown with crystal belt

I lost my emerald green satin evening gown yesterday around 3pm near the Grand Theatre on Main Street in Cartersville, Northwest GA. It's a floor-length gown, size 6, by Adrianna Papell, with a detachable crystal-embellished belt that gives it a little sparkle. The beading runs along the neckline and waist, and there's a tiny snag on the hem from dancing at the charity gala last weekend. It really matters to me—it was a gift from my grandmother and holds a lot of sentimental value; I’m hoping to get it back before my fundraiser next week.
