Creating these one-of-a-kind rings demands precision semi-tension threaded setting expertise unique to Barcelona's finest artisans. We carefully select each black onyx for optimal depth, luster, and uniformity before mounting through our signature technique that requires threading the gemstone ball onto specialized posts.
This sophisticated method, rarely seen in contemporary jewelry, ensures absolute security while showcasing the stone's natural beauty through 360-degree visibility. Our commitment to mixing "two different worlds of jewelry making" results in pieces worn forever, combining traditional goldsmithing with modern minimalist aesthetics.

All options hypoallergenic.

Q: What is semi-tension threaded setting?
This specialized Barcelona technique threads the gemstone ball onto precision-crafted posts, creating the illusion of suspension while ensuring absolute security. Unlike traditional settings, this method allows full 360-degree stone visibility without visible metal prongs.

Q: Why choose black onyx for statement jewelry?
Black onyx offers exceptional durability (7 Mohs), eternal mirror-like polish, and powerful grounding energy. Its deep black color creates striking contrast with all metal options while symbolizing strength, protection, and sophisticated confidence—perfect for your personal armor piece.

Q: What metal options are available?
Choose from sterling silver 925, 18K yellow gold, 18K white gold, or 18K rose gold. Each metal transforms the ring's character—rose gold adds warmth, white gold offers contemporary cool, yellow gold provides classic luxury, and silver delivers accessible elegance.

Q: How do I care for black onyx?
Black onyx requires minimal care—simply clean with warm water and soft cloth. Its natural hardness resists scratching while the polished surface maintains brilliance without special treatments.
