Gold-tone ruby pendant necklace found

I found a gold-tone pendant necklace this afternoon around 2:15pm, lying on a bench near the Old Faithful Inn in Yellowstone National Park, Wyoming. It's about 18 inches long, with a slim twisted chain and a small ruby heart pendant. The clasp is stamped with 'Kendra Scott' and there's a tiny engraving on the back with the initials 'A.S.' The necklace is in good condition with a few light scratches from travel. If anyone recognizes it, please get in touch—I’d love to help get it back to its owner.
