Letter Z figural brooch

This is a decorative figural brooch shaped like the letter Z, featuring a mixed-metal appearance with silver-tone and gold-tone finishes. The piece is heavily ornamented with textured elements, including twisted rope-like sections in a warm yellow-gold tone contrasted against rough, textured, silver-tone metal that resembles coral or organic growth. Small, round blue pavé-set rhinestones or crystals are embedded in clusters along the top horizontal arm and the bottom right corner of the letter, adding spots of vivid color. The reverse side reveals a standard pin stem and safety catch closure. There are no obvious maker's marks, signatures, or stamps visible in the provided image. The overall design exhibits a whimsical, mid-to-late 20th-century costume jewelry aesthetic, though the exact period, manufacturer, and material composition remain unverified without physical inspection or visible hallmarks. The condition appears generally good with intact stones and minor surface wear consistent with age and gentle use.

Based on what I can see in the photograph, this decorative figural brooch shaped like the letter Z displays a mid-to-late 20th-century costume jewelry aesthetic. The mixed-metal finish, textured organic-style metalwork, and blue pavé-set rhinestones suggest a playful, fashion-oriented accessory. However, I can't verify the exact material composition, manufacturer, or period from a photo alone, and would need physical inspection to confirm whether the metals are plated base metals or if any specific maker's marks are present on the reverse. Assuming the piece is a quality mid-century costume piece consistent with its visual style, comparable items typically trade in the $75 to $150 range on the secondary market, driven by steady demand for whimsical letter-themed novelty jewelry. If physical examination reveals the piece to be an unsigned reproduction, a modern replica, or simply made in the style of mid-century designer costume jewelry without attributable provenance, the value would likely decrease to the $25 to $50 range. To establish a stronger basis for attribution and confirm the piece's authenticity and construction quality, an in-person examination by a qualified specialist, detailed hallmark verification, and a closer look at the stone settings and pin mechanism would be necessary.
