Scratch-proof hardness

Tungsten carbide is the hardest ring material we stock. Here's why it doesn't scratch, bend, or tarnish.
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.
Pressed from tungsten carbide powder at 2,000°C, precision-CNC'd. Real weighted feel — nothing hollow, no plating to wear through.
If the metal ever cracks, chips, or fades — we replace it. One-time size swap free in the first 60 days.

Tungsten carbide 8mm ring with carbon fibre accent. The tungsten base gives the band its strength and everyday durability, while the contrasting details are framed as accents, inlays or finish elements rather than the core material. Comfortable to wear daily with a clean modern look.

Tungsten can't be resized — but in a true emergency it can be safely cut off. Best to nail the fit the first time.
