Woven Carbon Fiber Lightweight, durable, geometric pattern.

Redwood Interior Resin stabilized, hidden warmth.

Nine Grams The lightest of the twelve pieces.

Lifetime Warranty On material and workmanship.

Woven carbon fiber on the outside, stabilized redwood on the inside. Two materials that are not meant to meet.

Carbon is in airplanes, race cars, pro bikes. It's the material of silent performance.

Wood is in frameworks, violins, the hands of craftsmen. It's the material that has lasted ten thousand years.

Both in a nine-gram ring.

Interior	Resin Stabilized Redwood
Width	8 mm

Care

Carbon fiber is scratch-resistant and stable. The resin-stabilized interior wood needs to be hydrated a few times a year: rub a few drops of teak oil to preserve the color. Avoid prolonged immersion.

Description

Fibre de carbone tissée à l'extérieur, bois rouge stabilisé à l'intérieur. Deux matériaux que rien n'oblige à se rencontrer.

Le carbone est dans les avions, les voitures de course, les vélos de pros. C'est la matière de la performance silencieuse.

Le bois est dans les charpentes, les violons, les mains des artisans. C'est la matière qui tient depuis dix mille ans.

Les deux dans une bague de neuf grammes.

Entretien

La fibre de carbone est inrayable et stable. Le bois intérieur stabilisé résine demande à être hydraté quelques fois par an : frottez quelques gouttes d'huile de teck pour préserver la couleur. Évitez les bains prolongés.

Lifetime warranty

Each Maison Kardinal piece comes with a lifetime warranty on its structure: tungsten, steel, inlay setting. If the material fails, we replace it.

The warranty does not cover deliberate 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.

See full warranty details

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.

Legal warranty

The Maison Kardinal commercial warranty is in addition to the legal conformity warranty (two years in France) provided by the consumer code, and the warranty against hidden defects of the civil code. You retain all your rights.

Origin and signature

Each piece bears the MAISON KARDINAL signature engraved on the inside, using the logo's typography. This does not apply to 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 quality control before shipment from our storage facility.

Raw materials (tungsten, 316L steel, Gibeon meteorite, bourbon barrel wood, carbon fiber, opal) are sourced from certified suppliers.

Value

Method 1, With an existing ring

The most reliable method if you already own a ring that fits you well.

1

Choose a well-fitting ring

Select a ring that you wear comfortably on the desired finger. Make sure it is not too tight and does not spin.

2

Measure the inner diameter

Place the ring flat on a ruler and measure the inner diameter in millimeters (from one inner edge to the other).

3

Consult the chart

Transfer the measurement to the chart above or use the converter. If you are between two sizes, choose the larger size.

Method 2, With a string or strip of paper

Ideal if you don't have a reference ring.

1

Wrap the string around your finger

Take a string or a thin strip of paper. Wrap it around the base of the desired finger, passing over the knuckle.

2

Mark the crossing point

With a pen, mark the exact spot where the string crosses. The string should be snug but not tight; it should be able to slide over the knuckle.

3

Measure the length

Unroll the string and measure the length between the two marks in millimeters. This is your circumference. Enter it into the converter above.

Important Tips

Measure at the right time

Your finger size changes throughout the day. Measure at the end of the day, when your fingers are at their largest. Avoid measuring when you are cold (shrunken fingers) or after physical exertion (swollen fingers).

Our rings are comfort fit

All Maison Kardinal rings are comfort fit (rounded interior). They slide on more easily than standard flat-interior rings. If you are used to classic rings, your comfort fit size may be the same or half a size smaller.

Between two sizes?

Always choose the larger size. A slightly larger ring will be comfortable, while a ring that is too tight will be impossible to wear. Our tungsten rings cannot be resized, so choosing the correct size is essential.

Tungsten cannot be resized

Unlike gold or silver, tungsten is an extremely hard metal that cannot be enlarged or reduced. In case of an incorrect size, we offer a free exchange within 30 days.

Two materials, nine grams

Carbon fiber on the outside, stabilized redwood on the inside. The lightest of the twelve pieces.

Two materials that have no reason to meet, in a ring you'll forget you're wearing.

Silent performance

Carbon is in airplanes and professional bikes. Wood is in frames and violins.

This piece brings them together, with nothing else added.
