Diamonds are Jessica Simpson’s best friend! The singer, fashion mogul, and mom-to-be just launched her latest venture—a collection of diamond jewelry for Zales. “This collection has allowed me to create pieces that truly reflect who I am, and that can become a keepsake for lifetime,” Simpson said of her lineup, which includes bracelets, earrings, rings, and necklaces in rose gold, yellow gold, white gold, and silver. The accessories—131 of them—feature script Js forming butterflies, hearts, and crosses, and are available now for $79 to $799 on zales.com. See some of the offering in the gallery now.
