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 ring arrived within 24 hours. I was amazed when my partner called me at work. The rings I purchased are better than the images and seem to be of a very high quality. Thank you
