1960s Mexican Brutalist Brass & Onyx Handcrafted Collar Necklace

This is not a necklace. It's a manifesto.

Handcrafted in Mexico in the 1960s by a skilled artisan, this powerful Brutalist collar necklace is wearable sculpture at its most commanding. A heavily textured abstract brass bib anchors three large black onyx cabochons — bold, unapologetic, and utterly unforgettable. The heavy twisted torque collar rests against the collarbone with the quiet authority of a piece that knows exactly what it is.

The reverse tells the full story of its authenticity: Alpaca metal backing, thick hand-soldered joins, and the unmistakable stamp of "Hecho en México". Left unpolished, as serious collectors prefer — the rich aged patina is part of its soul.

• Era: Circa 1960s
• Origin: Handmade in Mexico
• Materials: Brass, Alpaca alloy, black onyx cabochons
• Condition: Excellent vintage. Fully intact, no fractures or loose elements.

A magnificent piece of wearable art for collectors of Mexican modernist jewelry, brutalist design, and avant-garde fashion history.
