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.

Titanium is one of the smartest materials you can put on your hand if you're active. It's lighter than steel but tougher than most, handles heat and sweat, and won't corrode or tarnish. This ring keeps its look for years without a lot of maintenance. The comfort-fit curve inside means it won't dig in after long hours on the tools. If you work with your hands and want a wedding ring you don't have to worry about, titanium is the practical pick.

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.
