Nicole Richie is set to launch her own line of jewelry. The socialite, who recently gave birth to her first child, is teaming up with Mouawad, who also produces Heidi Klum’s line of jewelry.

“It’s all costume jewelry,” Richie explains. “I like to play with jewelry and mix and match.”

Meanwhile, Richie and her boyfriend Joel Madden are concentrating on their baby daughter Harlow Winter. Richie has made very few public appearances since giving birth to her daughter in January. She recently admitted that she doesn’t like to be away from Harlow.
