Rhinestone cluster screw-back earrings

This pair of vintage costume jewelry earrings features a curved, multi-stone cluster design configured to sit along the earlobe or contour upward. The physical characteristics include a silver-toned metal base with noticeable darkening, tarnish, and patina consistent with age and previous wear. The earrings are set with small, faceted clear rhinestones of varying sizes, claw-set in prongs to form a dense, sparkling surface that catches the light with hints of prismatic color refraction, particularly visible in the larger stone at the end of the left earring. The backing mechanism utilizes threaded screw-posts and round screw-backs, indicating an older era of manufacture, typically popular prior to widespread clip-on or modern post adoption. There are no clearly legible maker's marks, stamps, or signatures visible in the photograph, meaning identification relies entirely on visual styling, construction methods, and materials. The condition shows surface wear, dullness of the metal settings, and age-related oxidation, though the stones appear largely intact based on the visual angle. Stylistically, the piece shares similarities with mid-20th-century costume jewelry designs, commonly associated with the 1940s to 1960s, though without physical inspection or hallmarked documentation, its exact maker, country of origin, and period of creation remain unverified.

Based on the visual evidence available in the photograph, I have evaluated this pair of vintage costume jewelry rhinestone cluster screw-back earrings. Based on what I can see, the earrings feature a multi-stone curved design set with small faceted clear rhinestones in a silver-toned metal base, utilizing threaded screw-backs. The piece stylistically aligns with mid-20th-century costume jewelry commonly associated with the 1940s to 1960s. I can't verify from a photo the exact composition, metal purity, or maker, as no legible maker's marks or signatures are visible. The condition exhibits visible surface wear, dullness, and age-related oxidation to the metal base. Assuming this style and period of mid-century costume jewelry, comparable items of this type typically trade in the $45 to $90 range within the secondary vintage market, driven by moderate collector demand for wearable period pieces. However, physical inspection would be needed to confirm stone stability, metal composition, and overall condition. If this item were determined to be a later reproduction, replica, or an unattributed copy 'in the style of' mid-century designs rather than a period piece, the value would likely decrease to the $15 to $35 range. To establish a more precise evaluation or confirm authenticity and exact era of manufacture, an in-person examination by a qualified jewelry specialist or expert appraiser would be required.
