Mesoamerican-style mother-of-pearl or abalone shell inlay mask sculpture

This decorative object appears to be a stylized mask sculpture constructed with mosaic-like inlays of iridescent mother-of-pearl or abalone shell (pua shell). The mask features distinctive stylized facial proportions, stylized square ears, cutout almond-shaped eye apertures, and an open rectangular mouth, elements consistent with Pre-Columbian or Mesoamerican artistic styles, particularly Mayan or Aztec stylized decorative art, likely produced as late 20th-century souvenir or art pottery/sculpture. The shell pieces display a vibrant, iridescent nacreous sheen featuring shimmering hues of green, blue, pink, silver, and gold. The shell mosaic tiles are fixed over a molded substrate or armature, possibly resin, composite, or stone, and the entire assembly is mounted onto a polished dark square base (appearing to be black marble, onyx, or polished resin). No visible maker's marks, signatures, or stamps are discernible in the photograph; identification is based strictly on visual and stylistic features observed. The item appears to be in good pre-owned condition with slight surface dust, minor visible grout/adhesive lines between mosaic pieces, and light handling wear on the display base.

Based on what I can see in the provided image, this object is a decorative Mesoamerican-style mask featuring an intricate mosaic of iridescent mother-of-pearl or abalone shell tiles mounted over a molded form and displayed on a polished dark stone or composite base. The stylized facial features evoke traditional Pre-Columbian motifs, particularly Mayan or Aztec funerary masks, though the materials and construction strongly suggest a mid-to-late 20th-century decorative art piece or high-end souvenir rather than an antiquity. From a photograph, I cannot verify the exact substrate material, the precise age, or whether the base is natural black marble, onyx, or resin. A physical inspection would be needed to confirm the structural integrity, test the shell inlays, and inspect for hidden maker's marks or signatures. Assuming this is a contemporary or vintage decorative sculpture created in the Mesoamerican revival style, market demand for similar iridescent shell mosaic decorative pieces typically supports an estimated retail value in the $150 to $300 range. The piece appears to be in good condition, showing minor grout lines and slight handling wear on the base, which is consistent with light display use. Should an in-person examination, material testing, or provenance documentation establish that the piece is by a recognized modern artist or studio, the value could increase. Conversely, if it is confirmed to be a mass-produced tourist souvenir, market value would likely align closer to $50 to $100. To firmly establish origin and materials, an expert in-person appraisal and scientific inspection of the substrate would be required.
