This tungsten carbide men's ring pairs a durable tungsten carbide base with a koa wood inlay. The koa wood inlay adds natural texture and warmth without taking focus away from the tungsten carbide base. Scratch-resistant and easy to wear day after day, it gives you a bolder look without losing the practicality tungsten is known for.

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.
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.
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.
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.
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.
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.
Every ring in our range is built to outlast the work it’s worn through. Here’s what comes with yours, and how we back it.
Not the right size or finish? Swap it within 60 days. Fee-free on in-stock rings over $90 ($10 under $90). Return postage is yours — tracked is safest.
Real heft in the hand. Nothing hollow, no plating to wear through. Same metal day one, day ten thousand.
If the metal cracks or breaks during everyday wear, we replace the ring. Plating and inlays wear naturally and aren't covered.
Dispatch
In-stock orders are usually dispatched within 1–2 business days (Monday to Friday) from Brisbane, Australia; made-to-order rings show their lead time above. NZ-wide tracked courier on every order.
