House of Harlow Sunburst Necklace in Labradorite and Gold by Nicole Richie. This 14kt yellow gold plated pendant features a starburst shaped raw labradorite stone detail on a 14kt yellow gold plated delicate long chain. The labradorite stone will appear slightly different in each necklace due to the use of the natural stone - no one is alike. House of Harlow Sunburst Necklace in Labradorite and Gold by Nicole Richie.
