Stainless steel
Updated on 10/2026 for a new, even more durable finish.
Assert your style with this stainless steel signet ring set with black onyx, a jewel with modern and elegant geometric design. Designed for both men and women, this customizable signet ring combines the depth of a black stone with the silver shine of polished metal. Its distinctive hexagonal shape gives it a strong character, ideal for those seeking an original and timeless piece.
At the center of this signet ring, a faceted hexagonal black onyx immediately draws the eye. Its geometric cut with sharp edges creates subtle plays of light, highlighting the stone's different facets. Surrounded by a hexagonal stainless steel setting, the onyx forms an elegant contrast with the shiny silver finish. Sculpted lines extending the central motif onto the ring's shoulders enhance its contemporary aesthetic.
Traditionally associated with strength, stability, and protection, black onyx adds a symbolic dimension to this creation. Its deep color and sophisticated appearance make it a stone particularly appreciated in bold jewelry, both masculine and feminine.
Made of stainless steel, this signet ring offers good resistance to corrosion and everyday wear, while requiring little maintenance. Its 10 mm width gives it a pronounced presence on the finger, while its rounded contours and smooth interior ensure comfortable wear. The polished finish highlights the curves and geometric details of the setting.
Thanks to its custom engraving option, this black onyx signet ring can feature a name, initials, an important date, or a short symbolic message inside the band. This customization transforms the ring into a unique jewel, perfect for preserving a precious memory or celebrating a special event.

Choosing the right engraving font is essential to ensure good readability and an aesthetic result that suits your jewelry. We offer 4 writing styles, each with its own specific characteristics.
Arial is one of the most compatible fonts. It adapts to almost all models and to many foreign languages. The result is clean, discreet and balanced, ideal for an elegant and timeless engraving.
Times New Roman offers a more traditional style while remaining very readable. It is perfectly suited for long engravings and guarantees excellent results on most jewelry.
JetBrains Mono is a monospace font: each character occupies the same space. This makes the engraving more visible and more pronounced. It is recommended if you want an original and easily legible engraving. However, it is not recommended for long sentences, as it takes up more space.
Manuscript (Pinyon) offers a classic and ancient style. It is suitable for lovers of decorative engravings. However, it is less legible because it is visually smaller. It is therefore not recommended for small areas in order to guarantee good readability.
Tip: If you're unsure, choose Arial or Times New Roman for optimal results and long-lasting engraving.
Choosing the right ring size is essential to ensure optimal daily comfort. The most reliable method is to measure an existing ring using a professional ring sizer. If you do not have professional tools, you can easily measure your finger size at home.
Take a flexible measuring tape, a sewing tape, or a thin strip of paper.
Wrap the tape or paper around the base of your finger. Tighten it firmly.
Mark the point where the ends meet, then measure the length using a ruler in millimeters.
The value obtained corresponds to the circumference of your finger. The French ring size directly matches this circumference expressed in millimeters.
Finger size may vary depending on temperature and time of day. A difference of one millimeter is generally not noticeable when worn.
If you hesitate between two close sizes, choose the size closest to your result rather than overestimating.
If in doubt, our customer service team is available to assist you.
