These classy earrings from DeLizza & Elster are from their highly sought after Juliana line, produced in 1967 and 1968. They were never marked as they were sold with paper hang tags. The only clues to the identity of these pieces is their construction.
These earrings feature two of those clues: the "fang" prongs on the stones along the top which show figure 8s on the back, and the large hole earring paddle, one of the few designs they used.
The last photo shows these in another colorway on the "Is it Juliana?" online database, item 3041.
Earrings measure 1.25" tall and 1" wide
Excellent condition, all stones present and bright, minimal finish wear.
