Measure the inside edge-to-edge of a ring you already own for the most accurate result. For wider bands (8mm+), sizing up is usually the safer choice.
Ring Sizing FAQ
We recommend sizing up. A ring that's slightly loose is more comfortable than one that's too tight, especially for wider tungsten bands.
Yes — fingers can swell slightly in heat and shrink in cold. Measure at room temperature, ideally in the evening when fingers tend to be at their largest.
Yes — wider bands (8mm and up) tend to fit more snugly than narrower ones at the same listed size. If you're between sizes and ordering a wide band, size up.

A matte black tungsten carbide ring with beveled edges, available in 6mm, 8mm, 10mm, and 12mm widths for men. This matte black tungsten carbide ring keeps the design simple and versatile, letting the width choice do most of the work in setting the overall look, from an understated 6mm to a bold 12mm statement piece.
A Matte Finish Built Across Every Width
The matte black tungsten wedding band finish is set into the tungsten carbide itself rather than applied as a coating, so it holds its non-reflective surface through years of daily wear without dulling further or needing to be reapplied. The beveled edges add a defined line along the profile at every width, keeping even the widest 12mm option from looking flat.
Choosing the Right Width for You
Narrower widths (6-8mm) read as more traditional, while 10-12mm options offer a bolder, more substantial presence on the hand. Since tungsten carbide fits more snugly at wider widths for the same numeric size, sizing up is generally the safer call if you're between sizes and leaning toward 10mm or 12mm.

No vague "premium materials" claims. Here's exactly what makes up every TungstenNation ring, layer by layer.
1
Tungsten Carbide Core
The structural body of the ring. This is where the hardness comes from — rated 8.5–9 on the Mohs scale, which is why it resists scratches that dull softer metals over time.
2
The Binder
Pure tungsten is too brittle for jewelry, so it's fused with a binder metal to hold the structure together. We disclose which binder is used in every listing — nickel or cobalt — instead of leaving it out.
3
Surface Finish
Color and texture (brushed, polished, matte) are set into the surface during manufacturing, not sprayed or plated on top — so it doesn't chip or fade with daily wear.
