White gold ring with bezel-set amethyst

I lost a slim 14k white gold ring with a bezel-set amethyst. It's about the width of a fingernail and has a tiny nick on the inner edge. Yesterday around 3pm, near the Riverside Market on Main Street in The Thumb, I must have slipped it off while tying my sneakers near the crosswalk. The inner band is engraved 'A.J.' and there’s a small scratch on the outside near the setting. It was a gift from my mom and means a lot to me—really hoping someone can find it.
