Vintage tiger's eye brooch

This is a vintage costume jewelry brooch featuring a central, polished oval cabochon of what appears to be natural tiger's eye gemstone, exhibiting the characteristic chatoyant golden-brown banding and silky luster. The stone is securely bezel-set within a textured, rope-twist inner frame. Surrounding this inner border is an ornate, pierced openwork outer frame crafted from a gold-toned base metal, possibly brass or alloy, adorned with scrolled, baroque-inspired motifs and dark accenting in the recessed areas to create contrast and an aged aesthetic. The overall physical structure displays an oval orientation with undulating, scalloped edges. Regarding visible condition issues, there are minor surface scuffs on the dome of the stone, consistent with moderate age and prior handling, and some slight tarnish or darkening on the reverse and recessed portions of the metal framework. There are no maker's marks, stamps, or signatures immediately visible on the front of the piece, suggesting the identification relies purely on visual characteristics of the materials and setting style. Based on the construction, design language, and materials, the piece is stylistically consistent with mid-to-late 20th-century costume jewelry, though no specific manufacturer or exact production year can be verified from the image alone.

Based on what I can see in the photograph, this vintage costume jewelry brooch features a polished oval tiger's eye cabochon set within a rope-twist bezel and an ornate, pierced gold-toned base metal frame with dark accenting. I can observe minor surface scuffs on the stone and slight tarnish on the reverse, which are consistent with age and moderate handling. However, I can't verify the exact metal composition or stone origin from a photo alone, and would need physical inspection to confirm these materials. There are no visible maker's marks or signatures, meaning the attribution to mid-to-late 20th-century costume jewelry relies entirely on visual style and construction cues. The estimated value range of $75 to $150 reflects typical market demand for vintage costume pieces of this type and aesthetic appeal. If the piece were to undergo in-person examination, hallmark verification, or expert appraisal and be found to be a modern reproduction, replica, or merely made 'in the style of' rather than period-appropriate, the value would likely decrease to the $25-50 range. Conversely, discovering a prestigious maker's mark upon physical inspection could increase its value, though such an attribution remains purely a working assumption until verified.
