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.

Three simulated diamonds mark this 8mm tungsten carbide promise ring, which is also listed with our engagement rings. The brushed satin finish keeps it understated while the stones add sparkle. Tungsten carbide resists scratches, and it cannot be resized, so check your US size.

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.
