Built for a lifetime.
Tungsten carbide is the hardest ring material we stock. Here's why it doesn't scratch, bend, or tarnish — and how ours is made.
Scratch-proof hardness
Tungsten carbide sits just below sapphire on the Mohs scale. 4× harder than titanium, 10× harder than 18k gold — meaning the ring you pick up on day one looks identical on day 10,000.
Heavier than gold
Each ring is pressed from tungsten carbide powder at 2,000°C and precision-CNC'd. The density gives it a real, weighted feel — nothing flimsy, nothing hollow, no plating to wear through.
Lifetime warranty
If the metal cracks or chips through a manufacturing defect in normal wear, we replace the ring once. Plating and inlays excluded.
Every ring arrives ready.

Not sure of your size?
Tungsten can't be resized — but in a true emergency it can be safely cut off. Best to nail the fit the first time. Three ways to check.
The details.
A polished 7mm tungsten band with two narrow grooves turned into the surface, spaced apart rather than paired at the centre. The grooves read as dark lines against the shine and give the band a machined, engineered look.
Nothing here is applied or plated: the detail is cut, so it stays put. Tungsten holds a polish under conditions that would dull softer metals, so the ring keeps its contrast through gym sessions, tool work and general knocking about. Comfort fit inside, 7mm across. A straightforward everyday ring for men who want a plain band with one small idea in it. Lifetime structural warranty on the metal.
