Sarah Jessica Parker was on hand for the unveiling of Halston's Spring 2011 collection last night (and modeling it head-to-toe) and while we loved her red-hot look, it was her necklace we couldn't take our eyes off of! Parker complemented her jersey dress with a white jade necklace with precious and vintage-painted wood beads from Lori Goldstein for Fred Leighton. The necklace is part of a 25-piece collection that the super-stylist designed for Fred Leighton. The collaboration, which debuted on Fashion's Night Out, features one-of-a-kind bead necklaces comprised of faceted diamonds, Tahitian pearls, vintage glass, sapphires, hand-painted Czechoslovak wooden beads and a Victorian crystal heart. The line ranges from $3,500 to $25,000 and is the fine jeweler's first-ever collaboration.
