Gold pendant necklace with initials 'A.J.'

I lost my gold pendant necklace yesterday around 3pm near the Kansas State Capitol on 10th Ave in Topeka. It's a slim 14k gold chain, about 20 inches long, with a tiny heart pendant about 1 cm across. On the back of the pendant are the initials 'A.J.' engraved in a delicate script, and the clasp area is a little bent with a faint scratch on the pendant's surface. This necklace was a gift from my grandmother and carries a lot of sentimental value; I really need it back.
