Lost gold pendant necklace with initials

I lost my gold pendant necklace yesterday around 3pm near Broadway Coffee Co. on Broadway Street in Scottsbluff. It’s a 14k yellow-gold pendant on an 18-inch box chain, with a tiny heart shape about half an inch tall. The front is engraved with the initials 'J.S.' and the back has a little star stamp. The chain has a slight bend near the clasp and the clasp feels a bit stiff to open. It was a gift from my grandmother, so it carries a lot of sentimental value, and I’d be really grateful to get it back if anyone finds it.
