Hart of Dixie season 3 features Peggy Li Creations handmade jewelry worn by Rachel Bilson, who plays Zoe Hart on the show.
In the season 3 premiere, Zoe wears my Spark Earrings http://www.peggyli.com/spark-earrings.html
If you're looking for the Horseshoe Charm necklace, I have something similar (the original is by Nashelle) in 14k gold-filled. http://www.peggyli.com/horseshoe-charm-necklace.html
Hart of Dixie also stars Jaime King and Kaitlyn Black.
