Oval Inlay Mother-of-Pearl Star Brooch

This is an oval-shaped decorative brooch or pendant featuring a complex inlay design. The central motif is an eight-pointed star or flower, meticulously constructed from diamond-shaped pieces of white mother-of-pearl. These segments exhibit a distinctive iridescence and chatoyancy characteristic of high-quality nacre. The star is set against a solid black background, which is likely polished onyx or a high-gloss cold enamel. The entire assembly is encased within a thin, silver-toned metal bezel, possibly sterling silver or silver plate, which provides a clean and modern structural border. The craftsmanship is highly precise, with tight seams where the organic shell meets the dark substrate. The item appears to be in excellent vintage condition with no visible cracks in the inlay, though there is a subtle patina and minor surface micro-scratching on the metal rim consistent with age. Based on the geometric aesthetic and material choice, the piece likely dates from the late 20th century, drawing inspiration from Art Deco revival or Southwestern inlay traditions. The lack of visible hallmarks in this view suggests a possible artisan piece or high-end costume jewelry design.
