Ring in Silver with Natural Black Diamond 3mm Size 18 | Rocas & Cristales

Exclusivity & Design — Black Diamond Ring 3mm: Hand-forged in rhodium-plated 925 silver, this size-18 ring by Rocas & Cristales sets three faceted, round-cut black diamonds of 3 mm each along a spare, considered band. The design keeps the composition simple and delicate, aligning the three stones in a row and securing each with claw prongs that let them stand out with real clarity. Conceived in our Córdoba workshop, the piece pairs traditional Argentine silversmithing with a contemporary design sensibility, equally suited to daily wear and to the most considered occasions.

Aesthetic Details — Black Diamond Ring 3mm: Black diamond, also known as carbonado, brings an opacity and metallic sheen that sets it apart from any other gem, while the linear arrangement of the three stones creates a spare, contemporary rhythm across the band. The rhodium plating deepens the dark tone of the stones, resulting in a piece of minimalist, quietly luxurious character. As a hand-forged work, it may carry subtle natural variations in the stones and in the silversmithing process — a mark of authenticity that distinguishes every Rocas & Cristales piece from any mass-produced counterpart.

Natural Stone Properties — Black Diamond Ring 3mm: Black diamond, also known as carbonado, is the most resilient natural variety of diamond — a fine-grained aggregate of amorphous carbon, graphite, and diamond formations that reaches the maximum hardness of 10 on the Mohs scale, unable to be altered by anything but another diamond. Natural black diamonds tend toward opacity, with a porous texture, metallic reflections, and a notoriously difficult polish, which makes every piece cut from this natural stone especially prized. It is linked to the root chakra for its capacity to lend strength, protection, and stability.
