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.

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.

Titanium 8mm ring with carbon fibre accent and koa wood inlay. The titanium 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.
