10mm Black Tungsten Ring — The Constant
10mm Black Tungsten Ring — The Constant
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 10mm black tungsten carbide ring with beveled edges and a matte finish, designed as a unisex band suited to engagement, wedding, or everyday fashion wear. The beveled edges add a defined, faceted line along the band without competing with the softer matte surface across the center.
A Refined Take on Black Tungsten
The matte surface resists showing fingerprints and light surface marks more than a fully polished finish would, while the beveled edges catch the light for subtle definition along the profile. Because the finish is set into the tungsten carbide itself rather than plated on, both the matte center and beveled edges hold their look through years of daily wear.

FAQ:
Is this ring suitable for both men and women?
Yes — the 10mm width and matte black finish work well as a unisex band, including for engagement or wedding pairs.
Will the beveled edges lose their definition over time?
No — because the finish is set into the tungsten carbide rather than plated on, the beveled edges hold their shape and contrast through years of daily wear.
Can this ring be used as an engagement ring?
Yes — its durability and refined finish make it a practical option for an engagement or wedding band, whether worn alone or paired with a matching ring.
How do I make sure I get the right size for a wider 10mm band?
Check our Size Guide before ordering — wider bands like this one tend to fit more snugly than narrower rings at the same numeric size, so sizing up slightly is often the safer choice.

What's Actually Inside Your Ring
No vague "premium materials" claims. Here's exactly what makes up every TungstenNation ring, layer by layer.
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.
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.
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.
