Brushed black tungsten carbide. An 18-carat rose gold groove runs along the ring, off-center.
The asymmetry is intentional. A single line, placed on the side, that catches the light like a thought.
Tungsten for durability. Rose gold for warmth. A single line, because one is needed.
As little as possible, to say the most.
Specifications

Care
Tungsten does not tarnish. The 18-carat rose gold groove may develop a slight patina over time, revealing its shade. A gentle wipe with a microfiber cloth is sufficient.
Description
Tungstène carbure noir brossé. Une rainure d'or rose 18 carats court le long de l'anneau, en décalage.
L'asymétrie est volontaire. Une seule ligne, posée sur le côté, qui attrape la lumière comme on attrape une pensée.
Le tungstène pour la durée. L'or rose pour la chaleur. Une seule ligne, parce qu'il en faut une.
Le moins possible, pour dire le plus.
Entretien
Le tungstène ne ternit pas. La rainure d'or rose 18 carats peut se patiner légèrement avec le temps, ce qui révèle sa teinte. Un essuyage doux au chiffon microfibre suffit.
Lifetime warranty
Every Maison Kardinal piece comes with a lifetime guarantee on its structure: tungsten, steel, and inlay setting. If the material fails, we replace it.
The guarantee does not cover intentional scratches, loss, or damage from extreme use. Tungsten is scratch-resistant in everyday use: it can crack under very strong mechanical pressure (dropping on concrete, heavy impact). In this case, we also replace it.
You wear the piece for twenty, thirty, fifty years. It remains functional. This is our commitment, and it is engraved in the MAISON KARDINAL signature engraved on each ring.
What is covered
The structure of the ring, against manufacturing defects.
Detachment of an inlay (meteorite, wood, opal, gold flakes) if the cause is a manufacturing defect and not an impact.
Abnormal tarnishing of a material guaranteed to be unalterable (tungsten, 18k gold).
Breakage of the hand-setting on Aurore and Galaxie pieces.
The interior engraving of the engraved MAISON KARDINAL signature, for life.
What is not covered
Intentional breakage or major impacts (crushing, violent impact against a hard metal object). Tungsten is very hard but brittle: a violent impact can break it cleanly.
Loss or theft of the piece.
Size modification. Tungsten cannot be re-sized (the material is too hard to be recut). In case of incorrect size, we offer a free exchange within thirty days of delivery.
Normal wear and tear of wood (Bourbon) or opal (Galaxie) if the piece is exposed to prolonged immersion, chemicals, or thermal shock.
How to activate the warranty
Step 1. Find the engraved MAISON KARDINAL signature inside your piece, or indicated on the provenance booklet received at the time of purchase.
Step 2. Send an email to contact@maisonkardinal.com with your engraved MAISON KARDINAL signature, two photos of the piece (overview and view of the defect), and a description of the problem.
Step 3. We will respond within 48 hours with return instructions.
Step 4. After receipt and expert assessment, we will replace the piece identically or repair it as possible. The interior engraving will be transferred to the new piece.
Lead time: between two and five weeks depending on the piece and material availability.
Fees
Warranty service is free of charge. Return shipping costs are your responsibility unless there is an error on our part.

Origin and signature
Each piece bears the MAISON KARDINAL signature engraved inside, in the logo's typography. This excludes pieces made from materials that cannot be engraved: the Damas Ring (forged steel) and the Carbon Ring (carbon fiber), for technical reasons.
The rings are made to order in our partner workshops specializing in tungsten carbide and Damascus steel. Each piece undergoes a quality control check before shipping from our warehouse.
Raw materials (tungsten, 316L steel, Gibeon meteorite, bourbon barrel wood, carbon fiber, opal) are sourced from certified suppliers.
