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.
