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. Tungsten carbide cannot be resized, so it is worth measuring twice.
Matte black, no glare, and a weight that stays put.
Atlas carried the heavens without asking who was watching. This ring works the same way: no shine, no show, just there. It is an 8mm tungsten carbide band brushed matte black on the outside and polished smooth on the inside. The domed shape curves away from the skin, so it reads as one clean black line. You feel the weight when you put it on, then you forget it. US sizes 7 to 12.

Details & specs
The band is made from tungsten carbide, one of the hardest materials used in jewelry. It resists the scratches of daily use far better than softer metals, and it does not rust. The outer surface is brushed to a matte texture in black, a plated finish, while the inside is left polished and marked Tungsten Carbide.
The profile is domed, so the edges curve away from the skin instead of sitting square against it. At 8mm (0.31 inches) wide, it covers a good part of the finger and keeps a steady, even black tone from every angle. No grooves, no stones, no inlay: just the shape and the finish.
How to wear it
Wear it alone on the ring finger for a clean, modern look, or on the index finger if you want it more visible. The matte black works with a black watch strap and a white tee, and it stays quiet under a shirt cuff with a suit. It suits daily wear, work and wedding-band duty for men who prefer black to metal shine.
Choosing your size
The ring comes in US sizes 7, 8, 9, 10, 11 and 12. Tungsten carbide cannot be resized, so measure a ring you already wear on the same finger before ordering. At 8mm wide, a band sits closer on the finger than a thin one, so if you are between sizes, take the larger one for an easier pass over the knuckle.
Why this piece
Hard-wearing by nature
Tungsten carbide is very hard and scratch-resistant, so the surface keeps its look through daily use.
Comfortable all day
The domed shape and polished interior mean no sharp edges against the skin during long wear.

Questions
Can the 8mm brushed black tungsten band stay on at the gym?
Yes. Tungsten carbide does not rust, so sweat and water are fine. Wipe the matte black with a dry cloth to clear oils and fingerprints.
Is the brushed black domed band a good wedding band?
Yes, for a man who prefers black to metal shine. The domed shape and polished interior keep it comfortable all day, with no sharp edges.
Which size should I take in the 8mm domed black band if he is between two?
The larger one, for an easier pass over the knuckle, since an 8mm band sits closer than a thin one. Tungsten carbide cannot be resized.
What does domed mean on a ring?
The outer surface curves from edge to edge instead of lying flat, so the sides fall away from the skin. On this 8mm band it reads as one smooth black line.
Is the inside black too?
No. The inside is left polished and marked Tungsten Carbide; the brushed black plated finish is on the outside.
Does it have a groove or a stone?
No. No grooves, no stones, no inlay: just the domed shape and the matte black finish.
How wide is 8mm in inches?
About 0.31 in. It covers a good part of the finger, noticeably wider than a 6mm band.
What happens if the size is wrong?
