Silver chain necklace with heart pendant

I lost my silver chain necklace yesterday around 3pm in downtown Fairbanks. I was near the Morris Thompson Cultural Center on Second Avenue when I realized it wasn't around my neck anymore. It's about 18 inches, a simple sterling-silver chain with a small heart pendant that has a tiny ruby dot and initials 'AR' engraved on the back; the chain is a touch tarnished but otherwise in good condition. This necklace is really sentimental—a gift from my grandmother—and I'm really hoping to get it back. If you've seen it, I'd be grateful to hear anything.
