Mid-Century Modern Brutalist Silver-Tone Square Pendant Necklace

This piece is a mid-century modern pendant necklace featuring a square-shaped geometric pendant suspended from a thick link chain. The pendant displays characteristic Brutalist design elements, showcasing a tiered, architectural motif with a raised central pyramidal stud. The metal appears to be a silver-tone alloy or sterling silver, possessing a textured, oxidized finish that enhances the depth of its abstract grid-like pattern. The pendant measures approximately 1.25 inches square and is attached to the chain via a stationary rectangular bail. The accompanying chain is a sturdy cable or curb link style with a lobster claw clasp, likely measuring 18-20 inches in length. In terms of condition, there is visible surface wear and minor scratching consistent with age and use, alongside a dark patina in the recessed areas which serves to highlight the relief. No obvious maker's marks are visible in the primary view, though such pieces often date from the 1960s to 1970s. The craftsmanship suggests a cast production, popular in mid-20th-century costume and artisan jewelry.

I have virtually examined this Mid-Century Modern Brutalist pendant necklace. The piece exhibits the raw, geometric abstraction synonymous with the 1960s-1970s jewelry movement. My visual assessment confirms several hallmarks of authentic period design: the tiered architectural motif, the use of a high-relief 'pyramid' stud, and an intentional oxidized patina that creates dramatic chiaroscuro within the grid-work. The condition appears to be 'Good to Very Good' for its era, with visible surface wear and oxidation consistent with the aging of silver-tone alloys or patinated sterling. The market for Brutalist artisan jewelry remains strong, particularly for sculptural, unisex pendants. While unbranded, the quality of the casting suggests a professional jewelry studio rather than mass-market manufacturing. Comparables for unsigned cast-metal Brutalist pieces typically fall in the $100-$180 range, whereas pieces confirmed as Sterling or by known makers (e.g., Guy Vidal or Robert Larin) command significant premiums. One major factor impacting value is the lack of visible hallmark or '925' stamp in the provided view. My appraisal is limited by the inability to perform a physical touch-test for weight or a chemical acid test for metal purity. To fully authenticate this item and potentially increase its valuation, an in-person inspection is required to check the reverse side and bail for stamps, and to verify if the base metal is solid silver or silver-plated pewter. Provenance regarding the original gallery or artist would also be necessary for a definitive attribution.
