14k white gold ring with small diamond, engraved

Yesterday around 3pm I realized my 14k white gold ring was gone. I was near the Chico Mall on Nord Avenue, in the parking lot behind the stores by the food court. It's a slim, 2mm band with a tiny bezel-set diamond, and the inside is engraved 'M.L. 2019'. It has huge sentimental value—my grandmother gave it to me, and I've worn it every day since. If anyone found it, I'd be forever grateful; it's really special to me and I'm hoping to get it back.
