"Thankyou so much. My partner wanted an engagement ring too and not only did you have what he was looking for but the quality is amazing and the delivery was super fast!"
"Hubby wanted something a little different and he absolutely loves it. It looks even better in person, and has a good solid weight to it. We ordered the wrong size to begin with, but the exchange process was easy, pain free, great communication from customer service and quick turn around. Highly recommended."
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.
From the outside this is a plain black 8mm band with a brushed surface. The purple lives on the inner sleeve, visible to you when the ring is off and to nobody else when it is on.
Hidden colour bands have become popular for a practical reason: they let you carry something personal without wearing it on show, which suits workplaces where jewellery is meant to be discreet. The black outer is a hard coating over solid tungsten, and the interior is shaped for comfort fit. Wide, dark and low-key. The tungsten core is backed by a lifetime structural warranty.

Extremely happy
Hubby wanted something a little different and he absolutely loves it. It looks even better in person, and has a good solid weight to it.
We ordered the wrong size to begin with, but the exchange process was easy, pain free, great communication from customer service and quick turn around.
Highly recommended.
Hi Erin. The neon with purple is certainly a different choice {and actually one of my favourite collections in our range}. I am over the moon that you love it and could not agree more about how much better it looks in person. If you end up with a photo, we would love you to tag us in it, seeing our designs on real hands is so much better :) Thank you again
