Gold-tone necklace with turquoise heart pendant

I lost my gold-tone necklace yesterday around 3pm near the food court at Cielo Vista Mall in El Paso. It's an 18-inch chain with a small turquoise heart pendant; the chain is a bit tarnished, and the back of the pendant has a tiny star engraving. There's also a tiny chip on the turquoise stone that might help identify it. It was a gift from my sister and means a lot to me—I'd really appreciate getting it back. If you found it, please let me know; I can meet you near the mall entrance by Dillard's to retrieve it.
