Black Diamond Ring, 3.5mm, in 925 Silver, Size 14 | Rocas & Cristales

Exclusivity & Design — Black Diamond Ring, 3.5mm: Hand-crafted in 925 silver at our Córdoba, Argentina atelier, this ring is set with a 3.5 mm black diamond, slightly larger than its companion piece but built from the same pared-down line. Every gem is evaluated in person by our artisans before setting, chosen for color, transparency, and cut above sheer size.

Aesthetic Details — Black Diamond Ring, 3.5mm: The marginally larger black diamond gives this piece a touch more presence while keeping the same restrained silhouette, equally suited to stacking as a cintillo band or wearing solo for full effect. The design moves easily between daytime and evening, and the hand-finished 925 silver carries a tidy, considered polish from the metal itself through to the final setting of the stone, with a slim profile that sits close to the skin and wears comfortably through the day.

Craftsmanship & Shipping — Black Diamond Ring, 3.5mm: Each Black Diamond Ring is handmade in Córdoba, Argentina, and inspected by our workshop before it ships to guarantee its quality. Complimentary worldwide shipping is included, and every piece is a limited edition of considered design rather than a repeated production run, verified by our team before it leaves the workshop.

Natural Stone Properties — Black Diamond Ring, 3.5mm: Black diamond, also known as carbonado, is formed from countless microscopic grains fused into a single dense body, its origin still debated among geologists, with some theories pointing to meteorite impact as the source of its formation. That fusion is precisely what gives it an opacity unlike any other diamond variety, reaching a full 10 on the Mohs hardness scale while remaining porous and largely free of the light refraction typical of colorless diamond. Sourced from Brazil and the Central African Republic, black diamond is associated with strength, protection, and the transmutation of negative energy, its resonance held in the root chakra and felt most keenly by those born under Capricorn.
