Silver necklace with sapphire pendant, 20-inch chain

I lost my silver necklace yesterday around 3pm near the Riverfront Park entrance on Spokane Falls Boulevard, right by the carousel. It’s a slender 20-inch sterling silver chain with a small circular pendant, engraved with the initials EM on the back and a tiny blue sapphire dot on the front. The chain has a couple of light scratches from daily wear, and the clasp still works. It was a gift from my grandmother, so it means a lot to me and I really want to get it back. If anyone found it, please contact me — I’d be forever grateful.
