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.

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. Three ways to check.
The details.
Green is the quieter of the hidden-colour options. Against the black outer it comes across as deep and slightly olive rather than bright, so even when the ring is off it does not shout.
The exterior is a brushed black finish over a tungsten core, 8mm wide, with the colour applied to the inner sleeve only. The interior is comfort fit, which is what makes an 8mm band sustainable for a full day. Popular with men who want their wedding ring to look like plain black metal on a job site. Lifetime structural warranty on the tungsten.

He loves it!
I bought my husband a new wedding ring after he lost his. He had no idea what I'd chosen and it was a complete surprise.
Purchase and delivery were easy and great!
My husband says; I love it! It is light and comfortable. Size fits perfectly and it looks great!
Amazing!!
Amazing quality, super quick delivery, and the return policy is awesome. Ordered the wrong size, used the ring sizer that came with the first ring to work out the right size, returned the ring and had the new one within a week. Thanks guys!
