In the 1950's Weiss was doing so well that the company contracted out to HOLLYCRAFT to help with production. I am going to make an educated guess and say that these pieces may very well be part of that output. The settings are the rich burnt gold with black antiqueing that HOLLYCRAFT is known for. The mid 1950's timeframe is suggested by the style.
The brooch is 3" x 2" and the clip earrings are 1 1/4" in diameter. The largest clear olive stones are 11 mm in diameter. They are multifaceted and the central brooch stone is gold foiled. The navettes are open back and sparkling. The hand set stones are in gold tiny beaded hoops antiqued settings. The brooch is articulated - twice. All pieces are signed. 1950's. Familial BOOK PIECE. The sister earrings are on page 132 of COSTUME JEWELRY collector guide by Judith Miller.
BEAUTIFUL VINTAGE over 50 years old. May have been worn once.
One of the navette stones has a clipped end. You can just see it in a close photo. I don't see HOW it may have broken but it is a clean cut, minor. The price reflects this slight imperfection.
