Basalt and Nacre Beaded Necklace with Mosaic Pendant

This is a statement necklace featuring a combination of black beads and a large, circular pendant. The necklace itself is composed of alternating segments: smaller, round, uniformly sized black beads forming chains, and larger, more substantial beads. These larger beads include both spherical and rectangular prism shapes, all appearing to be made from a matte or semi-matte black material consistent with polished basalt or a similar dark stone. The texture of these larger beads suggests a slightly uneven, natural finish typical of carved stone. The overall color scheme is monochromatic black for the beaded chain, providing a strong contrast to the iridescent pendant. The pendant is circular and appears to be constructed from numerous small, square or rectangular tesserae of nacre (mother-of-pearl) arranged in a mosaic or checkered pattern. The nacre pieces exhibit a pearlescent luster, reflecting light with hues of white, silver, grey, and subtle iridescence. There is a central circular cutout in the pendant, adding a distinctive design element. The pendant is attached to the beaded chain by a silver-toned wire bail, which appears to be a simple, open wire loop. The clasp of the necklace, visible at the top, is a silver-toned toggle clasp, common in contemporary jewelry for its ease of use. The condition appears good with no visible chips or major damage, though the matte finish of the black beads might show minor scuffs upon closer inspection. The craftsmanship indicates a handmade or artisan-crafted piece, likely from the late 20th or early 21st century, designed for a modern aesthetic.
