Silver necklace with turquoise moon pendant

I lost my silver necklace yesterday around 3pm after a stroll along the riverfront near the Tropicana Evansville on Riverside Drive. It's a slender 18-inch sterling silver chain with a small moon-shaped pendant inlaid with turquoise. The back of the pendant has a tiny 'JC' engraving and a faint scratch on the clasp. It’s sentimental because it was a gift from my mom and means a lot to me. I was grabbing coffee at a cafe near Riverwalk Park and then headed toward the Evansville Riverfront offices. If someone found it, I’d really appreciate getting it back.
