Artisan-style mixed media beaded necklace

This item appears to be an artisan-constructed necklace featuring a variety of mixed media components in shades of turquoise, blue, teal, and silver-tone metal. The necklace is designed in an asymmetrical, eclectic fashion, incorporating materials consistent with mother-of-pearl or dyed shell in various geometric shapes (rectangles, hexagons, and circles), alongside beads that resemble dyed turquoise or magnesite with visible dark matrix patterns. Large, rounded green focal beads with textured striations and openwork silver-colored metal beads with filigree or granulated details are also present. The piece is constructed on what appears to be a flexible metal wire or cord, finished with a silver-tone toggle-style clasp. There are no visible maker's marks, signatures, or quality stamps such as sterling silver (.925) hallmarks, so the piece is identified based on its stylistic aesthetic rather than a specific brand or maker. The condition appears to be good with minimal visible wear, though the materials suggest a contemporary or late 20th-century aesthetic. The overall craftsmanship is consistent with handmade or bespoke jewelry designs popular in the bohemian or eclectic fashion style.

Based on my examination of the provided images, I have evaluated this artisan-style mixed media necklace. The piece features an eclectic assembly of what appear to be dyed shell or mother-of-pearl, potentially stabilized magnesite or turquoise-colored stone beads, and silver-toned metal components. I cannot verify from a photo if the metal is sterling silver or a base metal alloy, as no hallmarks are visible; likewise, the stones would require a gemological test to distinguish between genuine mineral and high-quality synthetic or treated alternatives. The craftsmanship suggests a contemporary, handmade origin consistent with the bohemian aesthetic of the late 20th or early 21st century. The value estimate is based on the assumption that this is a unique, high-quality artisan piece using secondary market materials. If the silver-tone beads were to be confirmed as sterling silver through physical testing, the value would likely sit at the higher end of the $45–$85 range. Conversely, if the materials are found to be primarily plastic or plated base metal, the value would likely decrease to a $10–$20 range. The current market for 'unattributed' artisan jewelry is stable, driven by the visual appeal and 'one-of-a-kind' nature of the design rather than brand recognition. To confirm this valuation and the nature of the materials, I would recommend an in-person acid test for metal purity and a physical inspection of the bead porosity and temperature. For now, this remains a hypothesis based on visual stylistic cues.
