Silver necklace with moon pendant, 18-inch chain

I lost my silver necklace yesterday around 3pm near Bubblegum Alley on Higuera Street in downtown San Luis Obispo. It's a thin 18-inch sterling silver chain with a small crescent moon pendant. The pendant has a tiny star stamped on its lower curve, and the back is slightly scratched from wear. The clasp is stamped with an 'A' and looks a bit worn. It meant a lot to me because it was a gift from my grandmother, and I’m really hoping to get it back. If someone found it, please reach out— I’d be forever grateful.
