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.

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.
Same twin-groove idea, worked in matte. The whole 7mm face carries a brushed grain and the two cut lines show as shadow rather than sparkle, which makes the ring considerably quieter on the hand.
Tungsten carbide is dense and hard, so the grooves keep their definition instead of softening as the band wears. Comfort fit through the inside. This is the pick for men who want zero glare from a ring, whether that is for site rules, a preference for matte gear, or just not wanting jewellery to announce itself. Wears well with a steel watch. The metal carries a lifetime structural warranty.
