Vintage French Black Lampwork / Poured Glass Cube Drop Earrings

Vintage French mid-century drop earrings in black lampwork glass (colloquially often inaccurately referred to as poured glass) with a cabochon top, and a series of cube-shaped beads forming the drop. I’m not certain who they were made by - this earrings back and clip were used by a number of paruriers including Lina Baretti, Louis Rousselet, etc. Very fun, unusual earrings. One of the cube drop beads has a chipped corner - otherwise lovely condition for their age.
