This is a lovely rhinestone necklace with beautiful shimmering Aurora Borealis prong set round prong set rhinestones as the focal point. The 15 1/2 inch necklace has a hook closure that allows the necklace to be adjusted down in size as needed. The last rhinestone on the closure is marked Weiss on the yellow metal setting. This is a lovely vintage necklace that is perfect any time of the year!
