For the man who does his name proud.
Two minutes with a strip of paper or a soft tape and you will order the right size first time.
Shown in inches and US sizesMeasure at home in 2 minutes
You need a strip of paper (or a string or shoelace), a pen and a ruler.
With a ring that fits (most accurate)
- Lay a ring you wear on that finger on the ruler and measure the inside diameter, edge to edge, in inches.
- Find that diameter in the table below.
With a strip of paper
- Wrap the strip around the base of your finger: it must still slide over the knuckle.
- Mark where it overlaps, lay it flat and measure it in inches: that is the circumference. Find it in the table below.
Measure at the end of the day, when fingers are slightly larger.
No ruler? A bank card is 3.4" long: count how many fit along your strip.

Half sizes sit halfway between two rows (about 0.4 mm of diameter).
Good to know: measure at the end of the day, when fingers are slightly larger. Wide bands (8 mm and more) feel tighter: if you are between two sizes, take the larger one.
A dark oval stone, set flush, on a band you can feel.
Atlas took the weight without a word. This signet works the same way: solid, quiet, no flash. It is built from stainless steel with a polished finish, and the band carries a repeating ridged texture that leads to a flat, oval black stone set flush with the face. The shape is a classic signet, brought up to date. It comes in the natural color of the steel, in US sizes 7 to 13.
- Shower and gym: it stays on
- Flat oval black stone, set flush
- Ridged band, US 7 to 13
Details & specs
The ring is built from stainless steel, which gives it a substantial feel and resists rust and corrosion. That means it can stay on for hand washing, training and the rest of a long day. The finish is polished, in the natural silver color of the steel, so there is no plated band to think about and nothing that needs special care.
The face is a flat, oval black stone set flush with the steel for a clean profile, with no prongs to catch on a pocket. Along the band runs a repeating ridged texture that catches light and gives your fingers something to feel. Together they move the classic signet away from engraved crests and toward a sharper, modern shape.
How to wear it
Wear it on its own on the index or ring finger. The black face goes with a plain white tee, a dark knit or a navy blazer, and it sits well next to a steel watch. Because the stone is dark and flat, it stays understated enough for the office and still holds the eye at dinner. Keep other rings thin, or leave that hand bare.
Choosing your size
Available in US sizes 7, 8, 9, 10, 11, 12 and 13. A signet that fits well slides over the knuckle with slight resistance and sits comfortably at the base of the finger. Check his size with a ring sizer or a ring he already wears on the same finger. If he is between two sizes, take the larger one, since the face adds width on top.
Why this piece
A modern signet
A flat black stone and a ridged band replace the old engraved crest. Clean lines, nothing to explain.
Made to stay on
Stainless steel resists rust and corrosion, and the flush-set stone has nothing to snag. It handles daily life without special care.

Questions
Can I swim with the flush black stone signet on?
Not for long swims. The steel does not rust and the stone sits flush, so showers and the gym are fine, but take it off in the sea or the pool to keep the oval stone glossy.
How do I find his ring size?
Borrow a ring he wears on the same finger and compare it with a ring size chart, or have a jeweler measure him. The ring is offered in US sizes 7 to 13.
Is the band smooth or textured?
Textured. The band carries a repeating ridged pattern that you can feel and that catches the light, while the oval face stays flat and smooth.
Is the stone flat or domed?
Flat. The oval black stone sits flush with the face, so the profile stays clean with no prongs.
Is the steel plated?
No. It is polished steel in its natural silver color, the only color offered, so there is no plating to wear.
How is it different from a classic signet?
A classic signet carries an engraved crest. This one replaces it with a flat black stone and adds a ridged band, for a sharper, modern shape.
Does the ridged band feel rough?
It has a texture you can feel with your fingers, a repeating ridge that also catches the light, while the oval face stays smooth.
Is the stone covered by the warranty?
Yes, against manufacturing defects for 1 year: a stone that falls out without an impact is replaced. Accidental knocks and chemical damage are not covered.
