The necklace is adjustable and measures 16" long; the bracelet measures 7" long. This item is a vintage Trifari gold-tone bow bracelet, necklace, and clip-on earring set. The piece is part of the extensive and highly collectible costume jewelry line from the American company Trifari, known for producing high-quality, affordable pieces that rivaled fine jewelry in craftsmanship.  Brand: Trifari Material: The gold-tone finish is likely Trifanium, a patented, non-tarnishing metal alloy developed by Trifari after World War II, which is why many pieces from that era survive in excellent condition. Design: It features an open metal, polished finish in a floral motif. The design of your specific earring appears to be the back of a hollow or open-work flower/ribbon pattern. Marking: The signature "TRIFARI" is visible on the clip mechanism, along with a copyright symbol (©). The absence of a crown above the "T" suggests the piece likely dates from the 1970s or 1980s, after Trifari stopped using the crown symbol in that era. Value: Vintage Trifari pieces are sought after by collectors, with prices varying based on era, condition, and design rarity. Pieces from the 1950s-1960s designed by Alfred Philippe are generally the most valuable.
