Elegant cubic zirconia sparkling necklace

Elegant cubic zirconia double stranded necklace. See pics for secure clasp. Beautifully made. See pics for setting case. Not sure of the metal but I think it's rhodium as necklace hasn't tarnished in all these years. Gently loved but shows no sign of wear. Great for black tie parties, events, cocktails, and other times of celebration. Necklace measures approximately 15".
