Silver bracelet with amethyst charm

I lost my silver bracelet yesterday around 3pm near the Walnut Street Bridge entrance by Coolidge Park in downtown Chattanooga. It's a thin sterling silver chain about 6.5 inches long, with a small oval amethyst bead and a heart-shaped charm engraved with 'M' on the back. The clasp is a tiny lobster clasp that's a bit worn. It was a Mother's Day gift from my grandmother and means a lot to me; I'm really hoping to get it back.
