Gold-tone pendant necklace with turquoise charm

I found a gold-tone pendant necklace this afternoon around 1:45pm in the parking lot behind the Flagstaff Visitor Center on South San Francisco Street. The chain is about 18 inches, with a small heart-shaped pendant that has a turquoise inlay and a tiny star etched on the back. The clasp is a sturdy lobster clasp, and the necklace shows only light wear, with a bit of dust from the lot. It feels sentimental and I'd really like to get it back to its owner.
