Gold-tone heart pendant necklace with initials

I lost my gold-tone heart pendant necklace yesterday around 3pm near the Adair County Courthouse on Kirksville's downtown square. It's on a delicate 18-inch chain with a small heart pendant about 1/2 inch wide. Inside the heart is a tiny turquoise bead, and the back is etched with the initials 'M.L.' It was a Christmas gift from my mom, so it means a lot to me and I really hope someone picked it up and can hand it back. If you found it, please reach out.
