Ring in 18k Gold with Bicolor Ametrine, Faceted Cut, Size 18 | Rocas & Cristales

Exclusivity & Design — Ring with Ametrine: Discover one of the most exclusive pieces in the Rocas & Cristales collection: a size 18 ring crafted in 18k gold, centered on a faceted ametrine that naturally displays two colors within a single stone — amethyst violet on one side, citrine gold on the other. The solid gold setting warms both tones at once, and the faceted cut was designed specifically to maximize the natural dividing line between the two colors, a technical challenge few workshops manage to resolve with precision.

Aesthetic Details — Ring with Ametrine: Ametrine's natural chromatic split, clearly visible to the eye, results from temperature variations during its geological formation — a phenomenon that occurs in only one deposit on earth. The 18k gold accompanies this duality with a warm shine that visually unifies both colors. This is a collector's piece, made for those who value geological rarity as much as excellence in goldsmithing, equally at home in formal settings and everyday life thanks to its singular pairing of color and precious metal.

Craftsmanship & Shipping — Ring with Ametrine: Hand-forged in Córdoba, Argentina, this ring reflects the quality standards Rocas & Cristales holds for every piece that leaves the workshop. It ships with complimentary worldwide delivery, arriving ready to wear from the moment it reaches your door — a piece meant to be worn for years, and passed on for generations to come.

Natural Stone Properties — Ring with Ametrine: A natural pairing of amethyst and citrine within a single mineral specimen, ametrine forms when one deposit experiences differing temperatures during its formation. Its only commercial source in the world is the Anahí mine in Bolivia. Linked simultaneously to the Solar Plexus and Crown chakras and to Gemini and Libra, this natural stone is associated with the balance between intellect and spirituality, and with the harmony of opposites that coexist within a single person. Feeling its energy invites the wearer to integrate their own contradictions rather than resist them, finding in that coexistence an unexpected source of strength.
