Two long chain necklaces. Both silver and blue

Two gorgeous necklaces with blue and silver tone. They look great separately, and they look awesome when worn together. It all depends upon your taste and how you choose to pair them. The one with the silver bars is premier design and I have been unable to determine what the other one is. Both beautiful! Good pre-worn condition. Please review pictures for the best description available and also for the measurements. Happy shopping! OFFERS WELCOME *** FAST SHIPPING D1-20
