Vintage-style metal brooch with green stones

The item presented in the image appears to be a decorative brooch or pin crafted in a square shape, featuring a design that is stylistically consistent with mid-20th-century Asian export jewelry. The physical characteristics include a textured metal frame designed to mimic segmented bamboo stalks, enclosing an openwork interior pattern that resembles a stylized Chinese character, potentially representing longevity or a similar auspicious motif. Set into the frame are two dark green cabochon-cut stones, which are visually consistent with nephrite jade or similar green hardstones, positioned diagonally opposite one another in the upper right and lower left corners. The metal exhibits a warm, golden-toned finish with visible surface texture, possibly representing a gold-plated base metal or a lower-karat gold alloy, though material composition cannot be verified from a photograph alone. The item shows minor signs of age and handling, including slight surface patina and wear on the metal finish. There are no clearly legible maker's marks, signatures, or hallmarks visible in this image. Hedged language is used in the naming because no manufacturer stamps can be read directly, and the identification is based solely on stylistic features visible in the photograph, which would require physical inspection for full authentication.

Based on what I can see in the photograph, I have evaluated this vintage-style brooch featuring a bamboo-motif metal frame and green hardstone cabochons, stylistically consistent with mid-20th-century Asian export jewelry. I can't verify from a photo alone the exact metal composition, whether the stones are nephrite jade, or if the piece is a period original, as I cannot inspect maker's marks or test the materials directly. Assuming the attribution is correct and the materials are period-standard, comparable vintage export brooches typically trade in the $100 to $250 range within the current secondary market, driven by steady demand for mid-century costume and semi-precious jewelry. However, this valuation is conditional; an in-person examination, hallmark verification, provenance documentation, and scientific testing would be needed to confirm authenticity. If physical inspection reveals the item is a later reproduction, replica, copy, or produced simply 'in the style of' rather than being a period piece, the value would likely decrease significantly, often falling into the $30 to $75 range. The value estimate provided here assumes the hypothesized attribution, and the final market worth is dependent upon full physical authentication.
