Men's 925 Silver Signet Ring with Square Black Onyx and Greek Key Pattern

Faceted black onyx. The Greek pattern engraved in silver.

A square-cut, faceted black onyx stone, set like a gemstone, encased in an oxidized solid 925 silver frame. On each side, a row of claw-set black zircons frames the central stone. The sides reveal an openwork Greek pattern — geometric, precise, timeless. 5.7 grams. Size 67. A signet ring that carries the heritage of civilizations without being an imitation.

Faceted onyx is no ordinary stone. Each angle captures the light differently — a deep black that changes with the time and lighting. Worn on the finger, this signet ring catches the eye without seeking it out. This is what dark luxury is all about: understated on the surface, rich in detail.

Virtues of black onyx

A protective stone par excellence, black onyx has been used since antiquity to ward off negative energies and strengthen determination. It is associated with self-control, concentration, and resilience. In lithotherapy, it is renowned for grounding energy, stabilizing emotions, and providing the strength to move forward during difficult times. A stone for men who know where they are going.
