Ceramic figural brooch, unverified maker

This ceramic figural brooch features a distinctive fan or semi-circular shape depicting a stylized face with closed, serene eyes and a simple nose and mouth. The upper portion of the piece displays a vibrant turquoise and cobalt blue crackle glaze that transitions into a natural earth-toned rim, while the lower portion remains a matte, off-white bisque or unglazed ceramic surface. The piece appears to be hand-shaped, showcasing characteristic irregularities in its contour and surface texture consistent with studio pottery techniques. There are no clearly visible maker's marks, stamps, or signatures on the visible side, leaving the exact attribution unverified. The object exhibits minor surface crazing within the glazed area, which is typical of certain types of ceramic firing processes and age. The construction suggests it may function as a wearable art piece or decorative costume jewelry item, possibly dating to the mid-to-late 20th century based on the stylistic use of abstract figurative ceramics and reactive glazes. The overall design leans heavily into mid-century studio craft aesthetics, though the lack of an identifiable hallmark means the piece requires physical inspection to determine its full provenance and material composition safely.

Based on what I can see in the photograph, this ceramic figural brooch exhibits a mid-century studio craft aesthetic, featuring a stylized face, reactive turquoise and cobalt crackle glaze, and an unglazed bisque lower portion. However, I can't verify from a photo whether the ceramic body is earthenware, stoneware, or porcelain, nor can I evaluate the precise mineral composition of the glaze. Furthermore, because there are no clearly visible maker's marks or signatures on the surface, the exact attribution remains entirely unverified. The basis for the estimated value range of $150 to $300 assumes that the piece is a quality mid-20th-century artisan-crafted wearable art piece. General market demand for unique, studio pottery jewelry from the mid-century era is steady among collectors of wearable art and abstract ceramics. Minor surface crazing is observed within the glazed area, which appears consistent with age and firing processes, though I would need physical inspection to confirm whether this is expected aging or post-production damage. If physical inspection reveals the piece to be a later mass-produced reproduction, a modern replica, or a generic piece 'in the style of' mid-century studio craft rather than a period hand-shaped item, the value would likely drop to the $30 to $75 range. To establish a more precise evaluation and assess potential maker attribution, in-person examination by a ceramics expert, physical inspection of the pin findings and ceramic matrix, and potential provenance documentation or expert appraisal would be necessary.
