Roxanne Assoulin - The Royals Gold-Tone Crystal Necklace - Blue

With its stunning faceted blue crystals, Roxanne Assoulin's necklace looks like something the late Queen Elizabeth or Princess Diana (who were both big fans of sapphires) would have worn - hence the name 'The Royals'. It's cast from gold-tone metal and has a 3-inch extender, allowing you to adjust it to 17-inches at its longest.
