Black Opal Ring in Rhodium-Plated 925 Silver with Tourmaline, Size 18 | Rocas & Cristales

Exclusivity & Design — Black Opal and Tourmaline Ring, Size 18: This size 18 author ring is hand-crafted in rhodium-plated 925 silver, centered on an Australian black opal in a 9 x 7 mm oval cabochon and framed by faceted tourmaline in 6 x 3 mm and 1 mm cuts. The Rocas & Cristales design evokes a spider web, raising the opal at the center and encircling it with small pink tourmalines, carved, set, and polished entirely by hand in our Córdoba workshop.

Aesthetic Details — Black Opal and Tourmaline Ring, Size 18: The radial arrangement of navette-cut tourmalines toward the periphery creates a sense of movement that frames the black opal as the design's centerpiece. The result is a sculptural ring with genuine volume and a palette ranging from rose to multicolor. Its versatility suits both daytime looks and evening events, pairing naturally with other author pieces from the collection.

Natural Stone Properties — Black Opal and Tourmaline Ring, Size 18: Australian black opal is among the most coveted varieties of this natural stone, its flashes spanning the full color spectrum against a deep, dark body tone. Linked to the sacral and root chakras, it is said to awaken personal magnetism, passion, and inner transformation, holding an affinity with Scorpio and Gemini, for whom it heightens emotional intensity while lending serenity. Tourmaline is a structurally complex natural stone capable of forming in every hue of the spectrum, from colorless to the deepest black. Associated with the root chakra, it is traditionally credited with shielding against electromagnetic clutter and others' negative energy, increasing vitality and easing mental stress, and holds a particular affinity with Capricorn, to whom it offers protection and stability. Sourced from Brazil, it is often chosen as a daily companion for environments of high digital exposure.
