Vintage 1/20 12k Gold Filled Green Glass Beaded Necklace

This item is a vintage necklace composed of consistently sized, round, polished green glass beads. The beads display a vibrant, translucent to semi-translucent emerald green color, characteristic of older glass jewelry designed to mimic precious gemstones. Each bead appears to be individually hand-knotted on a string, a common feature in vintage and fine beaded jewelry that prevents beads from scattering if the strand breaks and adds flexibility to the piece. The necklace features a small, circular spring ring clasp, which, according to the provided context, is made of 1/20 12k gold filled material. This means that at least 1/20th of the item's weight is 12 karat gold bonded to a base metal. The gold fill gives the clasp a warm, yellowish metallic sheen. There are no visible maker's marks or signatures discernible from the image, but the craftsmanship of the individual knotting suggests a degree of care in its construction. The overall condition appears good, with no obvious chips or cracks on the glass beads, and the gold-filled clasp shows a slight patina consistent with age but no significant wear or damage. The piece likely dates from the mid-20th century, given the style of the beads and the noted gold-filled material often found in jewelry from that period. The consistent bead size and vibrant color indicate a well-made costume jewelry piece of good quality for its type.
