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.

Had an issue with sizing - sent it back and received a new one no problems at all. This ring split after a few weeks - advised Mens Rings Online and received a replacement no problems at all. Very easy to deal with. Highly recommended to my friends.
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.
