Ring in 18K Gold with Certified Paraiba Tourmaline, Size 18 | Rocas & Cristales

Exclusivity & Design — Ring with Certified Paraiba Tourmaline, Size 18: Hand-forged with 5 grams of 18K gold, this size 18 ring is led by a gemologically certified 1.12-carat Paraiba tourmaline, originally from Mozambique. It is one of the rarest, most intense, and most coveted gems in the world, set by Rocas & Cristales in an exclusive design with verified provenance.

Aesthetic Details — Ring with Certified Paraiba Tourmaline, Size 18: The electric blue, neon green, or intense turquoise hue of Paraiba tourmaline comes from trace copper within its structure, a rare phenomenon that sets it apart from any other gem in the world. Set over hand-worked 18K gold, the natural stone becomes the absolute focus of a piece that pairs the warmth of gold with the visual magnetism of this exceptional variety of tourmaline. To preserve its brilliance, avoid direct contact with perfume, creams, and cleaning products, and store the piece in a dry cloth or its original case when not worn. Paired with other pieces from the Rocas & Cristales collection, this authored jewel allows for layered looks with real personality, while never losing its status as a one-of-a-kind piece, cut and set by hand in our Córdoba atelier. Every stage of its making, from the selection of the natural stone to the final polish of the metal, is personally overseen by our goldsmiths, upholding a standard of quality that distinguishes Rocas & Cristales within Argentine fine jewelry.

Craftsmanship & Shipping — Ring with Certified Paraiba Tourmaline, Size 18: Hand-crafted in Córdoba, Argentina, this ring comes with a gemological certificate and our quality guarantee on its 18K gold. We offer complimentary worldwide shipping and, for clients in Argentina, the option to pay in 6 interest-free installments (Argentina only).

Natural Stone Properties — Ring with Certified Paraiba Tourmaline, Size 18: Paraiba tourmaline was discovered in the 1980s in the Brazilian state of Paraíba, though the specimen in this piece is native to Mozambique, where its chromatic magnetism owes to trace copper within the mineral lattice. As a natural stone, it favors mental and emotional clarity and is associated with authentic expression and sincere communication. It is linked to creativity, intuition, and openness to new stages of life, resonating with the throat and heart chakras. Though it can be worn by any sign, it is especially associated with Aquarius, for its innovative spirit; Pisces, for its sensitivity and intuition; and Libra, for the harmony and sophistication it conveys.
