Costume jewelry necklace and earrings set, attributed to Napier (not authenticated)

This costume jewelry ensemble features a linked necklace and a matching pair of drop lever-back earrings. The physical characteristics include silvertone metal settings with a twisted rope-texture bezel framing each stone. The primary visual element consists of cabochon-cut faux stones or resin inserts displaying a vibrant mottled teal and green coloration with an internal crackle or marbled pattern. The necklace is constructed with graduated oval links connected by jump rings, terminating in an adjustable extension chain. The earrings mirror the design of the necklace with matching oval cabochons in secure bezel settings suspended from lever-back closures. Regarding condition, the pieces appear well-preserved with intact plating and clean surfaces, though minor age-related wear or tarnish cannot be ruled out without close physical inspection. No maker's marks, stamps, or signatures are clearly legible in this photograph; the identification relies purely on visual style, assembly, and materials consistent with mid-to-late 20th-century costume jewelry manufacturing. The owner supplies the context that this is a Napier 19-inch necklace with matching earrings, but this user-attributed claim remains unverified and is not confirmed by any visible hallmark in the image. The style suggests vintage costume jewelry from the latter half of the 20th century, displaying standard commercial craftsmanship for mass-market fashion accessories.

Based on what I can see in the provided image, this costume jewelry ensemble consists of a 19-inch linked necklace and matching drop lever-back earrings featuring silvertone metal settings, twisted rope-texture bezels, and marbled teal and green resin cabochons. Per user submission: attributed to Napier. However, I cannot verify this attribution from a photograph alone, as no maker's marks or stamps are clearly visible to confirm the maker. This valuation assumes the owner's claim is correct and that the pieces are consistent with mid-to-late 20th-century mass-market fashion accessories. Comparable vintage costume jewelry sets of similar style and presumed attribution typically trade within this market range. Condition appears well-preserved with intact plating, but I would need physical inspection to confirm the absence of hidden tarnish, wear, or structural flaws. If the items turn out to be unattributed, unmarked reproductions, or made in the style of the brand rather than by the presumed maker, the value would likely decrease to the $15–$30 range. To confirm authenticity and the attribution, an in-person examination by a decorative arts specialist, physical hallmark verification, and detailed provenance documentation would be required.
