Vintage Garnet-like Screw-Back Dangle Earrings

This is a pair of vintage screw-back earrings, likely dating from the mid-20th century, possibly the Art Deco or Retro period given the screw-back mechanism. Each earring features a dangle design composed of dark red, translucent beads, which appear to be garnets due to their characteristic deep red hue and vitreous luster. The beads are arranged in a hierarchical fashion: a single larger, possibly faceted, bead at the top, followed by a cluster of smaller, irregular-shaped beads forming a berry-like or grape-like cluster at the bottom. The metal components, including the screw-back findings, are a warm gold tone, suggesting they are made of gold-filled metal, brass, or a low-carat gold alloy. There are no visible maker's marks or stamps on the screw-back mechanisms from the provided images, which is common for unsigned costume jewelry of this era. The condition appears to be good with a possible slight patina on the metal commensurate with age. There are no obvious signs of damage such as chips or cracks on the beads, or significant tarnishing that would detract from their appearance. The construction indicates these are crafted as dangle earrings designed for non-pierced ears. The assembly suggests wire wrapping or small pins securing the beads together and to the earring findings. The quality of craftsmanship appears to be standard for vintage costume jewelry, functional and decorative, rather than fine high-end jewelry.
