Our Barcelona artisan workshop has served clients from New York to London for over a decade. Each pair of filigree cufflinks begins with precision casting, followed by hand finishing where master goldsmiths apply the signature rope detail using techniques passed through generations of Spanish artisan jewelry makers.
The natural onyx undergoes careful selection and hand setting. This hybrid approach of advanced technology combined with traditional handwork ensures every pair meets international luxury standards.

Q: How should I care for gold and onyx cufflinks?
Wipe with a soft, dry cloth after wearing. For deeper cleaning, use mild soap with lukewarm water and dry thoroughly. Avoid soaking the onyx, as it is a porous stone. Store separately in the included pouch to prevent scratching.

Q: What makes these filigree cufflinks different from mass produced alternatives?
Each pair is individually crafted in our Barcelona workshop using solid 18K gold (75% pure gold) rather than plating that wears off over time. The filigree rope detail requires skilled handwork that machines cannot replicate.

Q: Are these unique cufflinks suitable for weddings and formal events?
Absolutely. The black and gold combination is a classic choice for wedding cufflinks, black tie galas, business meetings, and milestone celebrations. Onyx has represented dignity and authority for centuries.

Q: What is the symbolism of black onyx?
Black onyx has been treasured since ancient Egypt as a stone of protection, inner strength, and grounding. Roman soldiers wore onyx for courage. The gold and onyx pairing conveys success balanced with stability.

Q: How do I know if the gold is real?
Each pair features an 18K (750) hallmark stamp on the back of the cufflink, indicating 75% pure gold content. This official marking guarantees authenticity. Unlike plated pieces, solid gold maintains its appearance for generations with proper care.

Q: Why choose round cufflinks over other shapes?
Round gold cufflinks offer the most versatile and timeless silhouette. The circular form pairs effortlessly with any suit style, from classic business attire to modern slim-fit designs. Formal cufflinks in this shape have remained popular since the Victorian era precisely because they complement rather than compete with your overall look.

Q: Is there a sterling silver version available?
Yes, we offer the same Boxy Twins design in sterling silver for clients who prefer silver or seek a more accessible price point while maintaining artisan quality.
