Vintage-Style Rhinestone Screw-Back Drop Earrings

This pair of drop earrings features multi-stone cluster designs constructed from faceted clear stones, likely glass or crystal rhinestones, set within pronged silver-tone metal mountings. Each earring consists of a top stud element that attaches to a curved drop bar, supporting a stylized cluster or fringe arrangement of smaller stones below. The backings feature screw-back closure mechanisms designed for non-pierced ears, consistent with mid-20th-century costume jewelry manufacturing methods. The user notes describe these as 'screw type non pierced earrings', which aligns with the visible mechanical hardware. No maker's marks or hallmarks are clearly discernable in the photograph, so any specific maker or exact composition remains unverified without physical inspection. The metal shows minor oxidation and age-related wear, and the stones display light darkening or dust accumulation typical for vintage costume jewelry.

Based on what I can see in the provided image, this pair of vintage-style drop earrings features clear rhinestone multi-stone clusters set in silver-tone metal with screw-back closures. Per user submission, these are described as screw-type non-pierced earrings. This hardware style strongly suggests a mid-20th-century production era, roughly from the 1930s through the 1950s, when screw-backs were widely used. However, I cannot verify from a photo the precise metal composition, whether the stones are glass or crystal, or if any faint maker's marks exist on the findings. Physical inspection, metal testing, and loupe examination of the settings would be necessary to determine if these are unsigned costume pieces or work by a recognizable vintage manufacturer such as Coro, Weiss, or Kramer. Assuming these are unsigned mid-century costume jewelry in fair to good condition, the estimated market value is $20-40. The current secondary market for unsigned vintage rhinestone costume jewelry remains stable, driven largely by buyers seeking vintage aesthetic pieces for wear. Minor oxidation on the metal settings and light darkening of the stones, typical for age, slightly temper the value. If an in-person examination were to reveal a desirable maker's mark or confirm higher-end metalwork, the value could increase toward the $50-80 range. Conversely, if these are modern mass-produced reproductions made to mimic vintage hardware, the value would likely drop to under $10.
