Silver-tone moon pendant necklace

I lost my silver-tone moon pendant necklace yesterday around 3pm near the Holland Public Library on College Ave. It’s a delicate 16-inch chain with a tiny moon pendant and a small blue rhinestone near the bail. The back is engraved with the initials 'M.S.' and the chain has a bit of patina from everyday wear. This necklace is sentimental to me because it was a gift from my grandmother, and I really need it back. If you found it, please drop it off at the Holland Public Library desk or message me here—I'd be incredibly grateful.
