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.
The Black Celtic 8mm Mens Tungsten Ring pairs a black tungsten carbide base with engraved Celtic knot detailing for a ring that feels bold without looking overworked. The 8mm width gives it proper presence, while the polished comfort-fit interior helps it sit securely through long days at work or out at dinner. Tungsten carbide is highly scratch resistant, so it suits men who want a ring that keeps its crisp look with minimal fuss.
The Celtic pattern is decorative rather than raised, so it wears cleanly and does not catch like heavily sculpted bands can. Wipe it clean with mild soap and water and avoid hard impacts on edges, as tungsten is extremely hard but not flexible. If you are unsure on fit, start with our free ring sizer.
