Vintage 1970s Brutalist Spore Solid Cast Brass Belt Buckle Unisex

Vintage 1970s studio-art belt buckle featuring a dramatic biomorphic openwork design formed from clustered, molten-looking metal droplets. The sculptural web-like composition is often described as a spore or organic Brutalist motif and reflects the experimental artisan metalwork associated with the period. The buckle has a substantial, solid-cast feel rather than a lightweight stamped construction. Its warm brass or bronze tone is enhanced by deep natural patina and dark oxidation in the recessed areas, which add depth and emphasize the irregular handmade texture. The design is reminiscent of California Brutalist studio metalwork from the Jack Boyd era; however, the buckle is unsigned and unhallmarked, so no specific artist attribution is being made.
