Design Concept The Erebus signet is a dark meditation on shadow and permanence. Hand-sculpted in our Copenhagen atelier, it features two intricately carved skulls flanking a deep, midnight-black Onyx—a stone traditionally known for protection and grounding energy. This piece is the ultimate memento mori, balancing the cold weight of solid silver with the mirror-like depth of the volcanic gemstone.

Material & Craft

  • Gemstone: Genuine Natural Black Onyx (Cabochon cut).

  • Material: Solid 925 Sterling Silver, 100% recycled (Hallmarked).

  • Process: Hand-carved skull details, traditional lost-wax casting.

  • Finish: Deeply oxidized and hand-burnished to highlight the anatomical details of the skulls.

  • Origin: Locally handmade to order in Denmark.

Artisan Note Each Erebus ring is individually hand-sculpted. While the Onyx provides a consistent, deep black void, the silver textures and the depth of the oxidation will vary slightly from one piece to another, ensuring your ring is a unique, one-of-a-kind relic from the shadows.
