Cobalt Rex | 4mm Ceramic Ring with T-Rex Bone, Meteorite, & Blue Opal

A Sophisticated Tribute to the King of Predators

The Cobalt Rex is a refined, low-profile masterpiece that fuses prehistoric power with cosmic history. Housed in a sleek 4mm black ceramic band, this ring features a triple-threat inlay of authentic Tyrannosaurus Rex bone, silver-toned Campo del Cielo meteorite, and vibrant blue opals.

The deep cobalt hues of the opal provide a royal backdrop for the organic texture of the T-Rex fossil and the metallic sparkle of the meteorite. This is a durable, waterproof, and scratch-resistant piece designed for those who want a unique, meaningful story wrapped around their finger in a slim, modern width.

Materials and Origins

  • Authentic T-Rex Bone: Sourced from the fossilized remains of the Tyrannosaurus Rex. Each fragment shows unique mineralized patterns, ensuring your ring contains a genuine piece of the most iconic predator in history.

  • Campo del Cielo Meteorite: Authentic iron-nickel shavings from a massive meteorite strike in Argentina. These metallic fragments provide a bright, celestial sparkle that cuts through the blue opal.

  • Cobalt Blue Opals: We use premium crushed opals in shades of deep indigo and electric blue. They catch the light with a multi-dimensional "fire" that mimics the depths of the ocean or a distant galaxy.

Every ring is painstakingly assembled by hand in our California studio to ensure the ancient materials are perfectly showcased in this sleek 4mm profile.
