This is a D&E Juliana black diamond glass stone bracelet. It was made with three large oval shaped black glass stones with 3D designed black and clear chaton rhinestone clusters prong set on five linked rhodium plated rings. It also comes with a two inch security chain. It is listed in the book "Juliana Jewelry Reference" by Ann Pitman.
DeLizza & Elster designed and manufactured their jewelry from 1947 to 1990. Their well known bold design with colorful specialty stones collection was called Juliana. Later collectors refer to all D&E's jewelry as "Juliana." They never signed/stamped on their jewelry but used a paper tag. I love this kind of challenge to verify them by knowledge of construction.
Dimensions: 7.25 x 0.88 x 0.75 inch
