Vintage costume jewelry brooch and earring set

This is a vintage costume jewelry matching set consisting of one brooch and a pair of screw-back earrings, presented against a plain background in a digital image from an online marketplace listing. The physical characteristics include a gold-tone base metal construction, likely yellow gold-plated alloy, adorned with round faceted purple or magenta-colored paste stones and smaller clear rhinestone accents. The design features a stylized ribbon or bow motif with looping wirework and a ribbed central domed element on the brooch, complemented by smaller matching swirl motifs on the screw-back earrings. The condition appears well-preserved with intact stones and minor expected surface wear to the metal finish, consistent with mid-20th-century vintage costume pieces. The craftsmanship displays standard construction techniques of the period, such as prong-set rhinestones and soldered findings. No maker's marks, stamps, or signatures are directly legible in this photographic view. The owner's unverified supplemental notes mention brands such as Sarah Coventry and Trifari, but these attributions cannot be confirmed from the image alone without a physical inspection of any potential stamps on the reverse sides. Stylistically, the set aligns with mid-century fashion jewelry trends commonly produced during the 1950s or 1960s.

Based on what I can see in the provided digital image, this is a vintage costume jewelry set featuring a gold-tone brooch and screw-back earrings adorned with purple paste stones and clear rhinestones in a bow motif. Per user submission, the set is associated with brands such as Sarah Coventry and Trifari, though no maker's marks are directly legible in this photographic view. I cannot verify from a photo whether the set was produced by either of those prominent mid-century makers, and a physical inspection of any potential stamps on the reverse sides would be needed to confirm. The value estimate provided here assumes the owner's attribution is correct. In the general market, mid-century costume jewelry sets by known makers typically trade within this range, driven by collector demand for vintage bow and ribbon motifs. If the attribution is correct, the well-preserved condition with intact stones supports this valuation. However, if the set turns out to be an unattributed piece or made in the style of these makers without official markings, the value would likely decrease to the $30-50 range. To confirm authenticity and potential maker attribution, in-person examination of hallmarks and expert appraisal would be necessary.
