Built for a lifetime.
Tungsten carbide is the hardest ring material we stock. Here's why it doesn't scratch, bend, or tarnish — and how ours is made.
Scratch-proof hardness
Tungsten carbide sits just below sapphire on the Mohs scale. 4× harder than titanium, 10× harder than 18k gold — meaning the ring you pick up on day one looks identical on day 10,000.
Heavier than gold
Each ring is pressed from tungsten carbide powder at 2,000°C and precision-CNC'd. The density gives it a real, weighted feel — nothing flimsy, nothing hollow, no plating to wear through.
Lifetime warranty
If the metal cracks or chips through a manufacturing defect in normal wear, we replace the ring once. Plating and inlays excluded.
Every ring arrives ready.
