Square Silver-Tone & Black Agate Stone Copper Button Covers

These cufflinks combine deep black agate with polished copper for a crisp, geometric look. The square black stone sits as a smooth cabochon in a framed copper bezel, giving a clear contrast between the dark stone and the warm metal. The design is precise and refined, with no extra ornament.

• Metal Quality: Solid copper construction provides a stable frame that holds the stone securely and keeps its shape.
• Comfort Fit: Low-profile posts and smooth edges sit neatly under a shirt cuff for comfortable all-day wear.
• Everyday Use: Simple post design makes them easy to attach and removes the need for complex mechanisms.

Worn on a shirt cuff, the low-profile square looks clean and restrained next to a dress shirt or blazer sleeve. The polished copper frame catches the light while the black agate stays deep and even, so the pair works equally well with dark or light shirts. The balanced proportions suit both formal occasions and smart-casual settings.

A timeless addition to any man’s collection.
