The details.

This tungsten carbide men's ring pairs a durable tungsten carbide base with carbon fibre detailing. The carbon fibre detailing adds a technical contrast, while the tungsten carbide base keeps the ring durable and easy to wear. Scratch-resistant and easy to wear day after day, it gives you a bolder look without losing the practicality tungsten is known for.

Living with tungsten and carbon fibre inlay

The carbon fibre channel is sealed flush — no gap to trap dirt. Wipe across the inlay, not at it, to avoid lifting an edge over years. The tungsten outer brushes off scratches that mark softer metals.

Sizing notes for 8mm tungsten width

8mm tungsten feels heavy — that's the appeal. Sizing must be exact: tungsten can't be cut down later. Comfort-fit interior means slightly larger than a flat band. Use the NZ free sizer.

Comparing with plain black tungsten: the carbon texture

The woven carbon fibre catches light differently to a smooth black tungsten band — closer to a watch dial than a ring. Choose this for the technical look; plain tungsten for understated.

Q: Can scratched carbon fibre be repaired?

A: Not really — the inlay is a sealed composite. Light scratches barely show against the weave. Deep gouges need a full inlay replacement, rarely worth it.

Q: Does carbon fibre fade in UV?

A: The clear coat blocks UV well. NZ sun won't yellow it over normal wear years. Constant dashboard exposure would eventually dull it.

Q: Will it set off airport detectors?

A: Yes — tungsten triggers them. Pocket it before security, same as any metal ring.

I received my order within 2 days – amazing service provided. I have bought this ring as a 50th birthday present for my partner which isn’t until 27 August so have not been able to give it to him as yet – I have so been tempted but need to resist. I absolutely love the ring and I’m sure he will too. Now we just have to wait and see whether it fits.

I would give your company a 5 star rating.

Thanks for the excellent customer service, communication and speed of doing things. Recieved the replacement ring today and size etc is perfect. Many businesses don't focus on customer service although they pay lip service to the idea. I will certainly tell others and your products are quality items. Nothing was too troublesome for you..well done. I will also be back to purchase in the future.

Hello,

Just want to say I am extremely happy with the purchase. I had to return to resize and this process went seamlessly and I got the ring before my partner's birthday. Quality is superb. My partner is a painter sandblaster and the tungsten ring is still perfect and he wears it every day in the mines. Thanks you so much!!

Caring for your Carbon Fibre ring

Carbon fibre rings are layered woven carbon set into a resin matrix, often inlaid into a titanium, tungsten or ceramic outer sleeve. The carbon itself is inert — it won't tarnish, rust or react with skin, chlorine or saltwater. Clean with warm soapy water and a soft cloth; skip ultrasonic cleaners and harsh solvents like acetone, which can dull the resin over time.

Carbon is light and tough but the resin layer can chip on a sharp impact, so take the ring off for heavy lifting and contact sports. Most carbon rings cannot be resized — the weave runs continuously around the band — so getting sized right at order time is important. Stored in a soft pouch away from direct sunlight, the deep black pattern stays sharp for decades.

Common questions about Carbon Fibre rings

Are carbon fibre rings durable enough for daily wear?

Yes for office and light-trade wear — carbon fibre composites are stronger than titanium by weight and won't corrode. They can chip on a sharp impact (drops onto tile, hammer strikes), so heavy tradies often prefer tungsten or titanium for full-time site work.

Will a carbon ring fade or change colour?

No — the weave pattern is set into UV-stable resin and the colour is the carbon itself, not a coating. Avoid leaving it on a sunny car dash for weeks at a time, but normal NZ outdoor wear won't fade it.

Can a carbon fibre ring be resized?

Most cannot — the woven layers run continuously and can't be cut and re-joined like metal. Order your exact size; if you're between sizes, go up by a half. NZ jewellers will size your finger for free.

Is carbon fibre hypoallergenic?

Yes — pure carbon and cured epoxy resin are both biologically inert, with no nickel, copper or other common allergens. If the ring has a metal sleeve (titanium or tungsten), check that's hypoallergenic too — both of those are.

Considering alternatives?

Carbon often pairs with — or competes against — titanium rings, which give a similar modern, lightweight feel with a metallic finish instead of a woven black look. Titanium is easier to resize and slightly more impact-tolerant; carbon wins on distinctive pattern.
