How to measure

  1. Wrap a strip of paper or string around the base of your finger.
  2. Mark where it overlaps and measure the length in mm: that is your circumference.
  3. Or measure the inside diameter of a ring that already fits you.
  4. Between two sizes, take the larger one, especially for wide bands.

Description

This onyx signet ring sets a square of deep black onyx into a polished stainless steel band with softly rounded shoulders. It is a timeless men's piece: graphic, sober and confident, with a presence that does not need to raise its voice.

The 13 mm face sits flat on the finger and catches the light on its beveled edges, while the black stone keeps the overall look restrained. Choose the silver tone for a cool, modern feel or gold for a more classic, heritage spirit.

How to wear it

Traditionally worn on the little finger, a signet ring looks just as natural on the ring finger or index for a more contemporary take. Keep it as your only ring for a sharp, minimal hand, or pair it with a slimmer oval signet ring on the other hand. For a bolder mood, it sits well next to a sculpted lion ring. Discover the rest of our men's signet rings to complete your collection.

It works with a navy suit as well as with a leather jacket and jeans: the black stone echoes a dark watch strap, belt or shoes. An onyx signet ring is also a classic gift for a graduation, a wedding or a milestone birthday.

Care

Remove your ring before lifting weights, doing manual work or swimming to protect the stone from knocks. Wipe the steel and the onyx with a soft, dry cloth to remove fingerprints, and avoid contact with harsh cleaning products. Store it separately from other jewelry so the polished surface stays free of scratches. Our guide on how to clean gold jewelry is useful for the gold version.

N° 04

Finding your size

A signet ring has a wide face, so it fits a little tighter than a thin band: if you are between two sizes, choose the larger one. Measure the finger you plan to wear it on with our ring size chart, as the little finger is usually two to three sizes smaller than the ring finger.

Questions

Good to know

Materials, sizes, shipping and returns: the answers to what you ask us most.

On which finger should I wear it?
Traditionally on the little finger, but many men now wear it on the ring finger or index. Choose the finger where it feels most natural to you.
Silver or gold?
Silver feels modern and pairs with steel watches; gold has a more classic, heritage spirit and pairs with gold-tone accessories.
Is the ring heavy?
It has the reassuring feel of a signet ring with its 13 mm face, while staying comfortable for all-day wear.
