Gold ring with emerald and initials inside

I lost my 14k yellow gold ring with a tiny emerald bezel yesterday around 3pm. It's a slim size 6 band with an 'LJ' engraving on the inside and a small scratch along the edge. I was at Riverfront Park in downtown Mankato, Southwest Minnesota, near the bridge and Front Street after grabbing coffee. This ring was a gift from my mom and has a lot of sentimental value, so I'm really hoping it turns up. If you found it, let me know.
