Gold-tone necklace with heart pendant, lost near mall

I lost my gold-tone necklace yesterday around 3pm near the main entrance of the Columbia Center Mall in Kennewick. It's a 16-inch chain with a petite heart pendant, about 1/2 inch wide, and it has a tiny pink crystal on the front. The back of the pendant is engraved with an initial 'A', and the chain looks a little bent near the clasp from daily wear. It was a gift from my sister and has sentimental value, so I'm really hoping it turns up. If you found it, please email me at [email protected] to verify the engraving and the chain length.
