This is an original Roberto Otazu necklace. I purchased it new for the Holiday season several years ago, but never wore it. Roberto is an Argentinian artist whose extraordinary jewelry was featured in Sex in the City and in Sex in the City 2. He designs for many Hollywood Stars; Lady GaGa being one of his favorites. The pictures really don’t show the sparkle of the Swarovski crystals. It is a remarkable necklace. $600. new. Thank you for looking!
