Overview
These striking 'door-knocker' style earrings feature a bold geometric silhouette with a distinctive acid-etched or 'tortoise' patina. The oversized scale and raw, industrial finish are hallmarks of the late-century Brutalist movement in wearable art.
Story
The 1970s saw a rebellion against delicate jewelry. Artists used acid and fire to create these 'organic-industrial' textures, turning brass into something that looks like ancient, unearthed treasure.
Maker / Origin
While unsigned, these reflect the influence of designers like Robert Larin or the studio craft movement, where jewelry was treated as miniature sculpture rather than mere decoration. These makers valued the 'honesty' of the metal and the unique patterns created by chemical reactions.
Condition & Value
The earrings show significant surface oxidation and patina wear, which is actually desirable in this style as it enhances the 'relic' look. The posts appear intact, though one shows slight bending. This natural aging supports the vintage attribution. Unsigned studio brass pieces in this bold style typically sell in this range.
