Built for a lifetime.

Tungsten carbide is the hardest ring material we stock. Here's why it doesn't scratch, bend, or tarnish.

9MOHS

Scratch-proof hardness

Sits just below sapphire on the Mohs scale. 4× harder than titanium, 10× harder than 18k gold — the ring looks identical on day 10,000 as day one.

2x

Heavier than gold

Pressed from tungsten carbide powder at 2,000°C, precision-CNC'd. Real weighted feel — nothing hollow, no plating to wear through.

The details.

This carbon fibre ring is built like an aircraft panel — strong, light, and technically impressive. The woven carbon pattern is genuinely structural, not cosmetic, giving the ring rigidity without adding weight. This one comes in a 8mm width — Non-conductive, corrosion-proof, and hypoallergenic. It'll handle daily wear without picking up surface scratches the way polished metals do. The dark matte finish works well as standalone or as an inlay combined with titanium or tungsten. Good for blokes who want something that looks technical and performs to match.

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.
