8mm Brushed Black Tungsten Carbide Ring
£53.99
Tungsten carbide · Black finish · 8mm width · Brushed exterior · US sizes 7-12
Matte black weight that stays put.
An 8mm band in tungsten carbide, finished matte black on the outside and polished smooth on the inside. The domed shape sits close to the finger, so it reads as one clean black line instead of a shiny ring. You feel the weight when you put it on, then you forget it is there.
- ✓Tungsten carbide resists scratches through daily wear
- ✓Brushed matte black exterior, no glare
- ✓Domed profile with polished interior surface
Full description+
The piece
The band is made from tungsten carbide, one of the hardest materials used in jewelry. The outer surface is brushed to a matte texture in black, 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 wide, it covers a good part of the finger and keeps a steady, even black tone from every angle.
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 over metal shine.
Choosing your size
The ring comes in US sizes 7 through 12. Because tungsten carbide cannot be resized, 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, go up half to one size.
Why this piece
-
01Hard-wearing by natureTungsten carbide is very hard and scratch-resistant, so the surface keeps its look through daily use better than softer metals.
-
02Matte, not flashyThe brushed black exterior absorbs light instead of reflecting it, which keeps the ring understated even at 8mm wide.
-
03Comfortable on the handThe domed outer shape and polished inner surface mean no sharp edges against the skin during long wear.

Questions
Will the black finish wear off?
Tungsten carbide is highly scratch-resistant, so the surface holds up well to daily contact. Like any black finish, avoid abrasive cleaners and hard knocks against stone or metal.
How do I care for it?
Wipe it with a soft, dry cloth to remove oils and fingerprints. Remove it before heavy lifting or gym work, since tungsten carbide is hard but can chip under sharp impact.
Is this a good gift?
Yes, it is a simple black band that suits most wardrobes. The key is the size, so check a ring he already wears on the same finger before choosing between US 7 and 12.

Find your size
All Atlas pieces are crafted to true men's proportions. Measure twice, wear forever.
How to measure: wrap a strip of paper around the base of your finger, mark where it overlaps, then measure the length in mm. That's your inner circumference.
| Atlas size | EU | US | UK | Diameter (mm) |
|---|---|---|---|---|
| S | 54 | 7 | N | 17.3 |
| M | 57 | 8 | P | 18.1 |
| L | 60 | 9 | R | 19.0 |
| XL | 63 | 10 | T | 19.8 |
| XXL | 66 | 11 | V | 20.6 |
Tip: measure at the end of the day when fingers are slightly larger. Knuckle wider than the base? Size up.
How to measure: wrap a soft tape around your wrist where you'd wear a watch. Add 1cm for a comfort fit, 2cm for a relaxed drape.
| Atlas size | Wrist (cm) | Bracelet length (cm) |
|---|---|---|
| S | 15.5–16.5 | 17.5 |
| M | 16.5–17.5 | 18.5 |
| L | 17.5–18.5 | 19.5 |
| XL | 18.5–19.5 | 20.5 |
Most men: M (16.5–17.5cm wrist) is our best-selling size.
How to wear: chain length is measured tip-to-tip. Below: how each length sits on a 6'0" frame.
| Length | Sits at | Best for |
|---|---|---|
| 45cm / 18" | Collarbone | Tucked or under a tee |
| 50cm / 20" | Just below collarbone | Most versatile · best-seller |
| 55cm / 22" | Mid-chest | Layered with a pendant |
| 60cm / 24" | Lower chest | Statement chains |
Tip: when in doubt, 50cm is the universal Atlas length — clean over a tee, sharp under a collar.
