Ring in Silver with Natural Black Diamond and White Sapphire Size 18 | Rocas & Cristales

Exclusivity & Design — Black Diamond White Sapphire Ring: Hand-forged in rhodium-plated 925 silver, this size-18 ring by Rocas & Cristales centers a faceted, round-cut black diamond of 5.2 mm accompanied by 1 mm white sapphires. The design is spare and considered, setting the diamond alone at the center while the sapphires trace a double line along the band that frames the principal stone. 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 White Sapphire Ring: The contrast between the deep opacity of the central black diamond and the glass-clear brilliance of the surrounding white sapphires creates a composition of real visual impact, while the double line of sapphires brings movement and luminosity to the band. The rhodium plating unifies both stones under a single cool, sophisticated shine. 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.
