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.

If you want a ring that looks the same in ten years as it does today, tungsten carbide is hard to beat. The scratch resistance is exceptional — general daily wear, keys in the pocket, knocks on the workbench. This one comes in a 8mm width — It has a satisfying solid weight without being uncomfortably heavy. The polished surface keeps its shine without replating. Note that tungsten can't be resized, so get your measurement right. Good for blokes who want something tough and permanent.

Beautiful ring!

Theresa D. Verified buyer

I bought this for my fiancé as his wedding ring. The ring looks just like the photo presented. Slightly heavy ring but you can tell it’s very sturdy and durable. The infinity sign is beautifully designed. This is exactly my fiancé’s style.
