The details.

If a ring that looks the same in ten years matters to you, tungsten carbide is the pick. The scratch resistance is exceptional — harder than most materials you'll come across in daily life. Available in 6mm — The dense, heavy feel gives it a premium quality that lighter metals don't match. Polished finish stays polished. Bear in mind tungsten rings need to be sized correctly upfront — they can't be resized later. For a permanent, tough ring that holds its look through an active Kiwi lifestyle, tungsten delivers.

Caring for the 6mm brushed tungsten band

Tungsten will not scratch from keys, tools, or rope, but the brushed grain can polish up at knuckle contact. Wipe with warm soapy water; never use abrasive cleaners that round off the brush lines.

Sizing notes for 6mm tungsten

6mm is the middle ground — heavy enough to feel substantial, narrow enough to wear daily. Tungsten cannot be resized later, so use the free NZ sizer twice across different days.

Brushed 6mm tungsten vs polished tungsten

Brushed hides hairline marks; polished shows them but takes a deeper shine. Pick brushed if your hands are in tools all day. See the tungsten range for the full polished line-up.

Q: What if I drop it on concrete?

A: Tungsten is hard but brittle — a sharp drop on tile or concrete can chip it. Take it off before workshop floor work.

Q: Why can't tungsten be resized?

A: The hardness that makes it scratch-proof also makes it impossible to stretch or compress. Replace at trade-in price if your size changes.

Q: Does brushed dull over a year?

A: The texture can soften at the knuckle. A jeweller can re-brush with a fine wheel for a small fee.

Beautifully packaged for giving as a gift and the updates from MRO during and after delivery were helpful and informative, reassuring me that my item was in great hands the whole time. Would definitely recommend!

I have bought the ring for a wedding anniversary gift on the 29th Feb. It is so nice and I have shown many people in the office - some newly engaged and recommended your website and great service.

My husband had lost his wedding ring and this was a replacement it was exactly as described and the perfect fit and as it was a little wider than his original ring I don’t think he will lose this one. I was really impressed with the delivery time as valentine’s day was fast approaching. I would definitely look at Mens Rings Online again.

Caring for your Tungsten ring

Tungsten carbide is one of the hardest metals used in jewellery, scoring around 9 on the Mohs scale, so day-to-day scratches from desks, tools and gym equipment rarely leave a mark. Wipe the ring with a soft cloth and warm soapy water every week or two to lift skin oils and soap residue, then dry it fully before putting it back on. Avoid dropping it on tile or concrete — tungsten resists scratching but can chip or fracture from a hard impact.

Take the ring off before heavy lifting, contact sports or rock climbing, since unlike softer metals tungsten cannot be cut off with standard ring cutters in an emergency (medics use a vice-grip crack method instead). The polish holds for years without re-buffing, and the ring will not tarnish, oxidise or react with chlorine in pools or spas.

Common questions about Tungsten rings

Is tungsten a good metal for a men's wedding ring in NZ?

Yes — tungsten is the most scratch-resistant ring metal sold in New Zealand and holds its mirror polish through years of trades work, farming or office wear. It sits in the mid-price band (well under most gold options) and ships free across NZ. The main trade-off is that it cannot be resized, so getting the fit right at order time matters.

Can tungsten rings be cut off in an emergency?

Yes, but not with a standard ring cutter. NZ emergency departments and jewellers use locking pliers or a vice-grip to apply pressure at two points until the ring cracks cleanly into two halves, which actually comes off faster than sawing through gold. Always tell medical staff the ring is tungsten so they grab the right tool.

Will a tungsten ring turn my finger green or black?

No. Quality tungsten carbide rings use a nickel-free binder and are hypoallergenic, so there is no oxidation transfer to skin. If you see grey marks it is usually a metallic-soap reaction from heavy hand-cream or sunscreen — wash with warm water and it lifts off.

How do I get the right tungsten ring size in NZ?

NZ ring sizing uses the same A–Z letter scale as Australia and the UK, so any NZ jeweller can size you for free. Because tungsten cannot be resized after manufacture, we recommend getting sized at the end of the day when fingers are at their largest, and ordering a half-size up if you work outdoors in cold weather.

Considering alternatives?

Buyers weighing up tungsten often also look at titanium rings — both are hypoallergenic and modern, but titanium is roughly four times lighter on the finger while tungsten holds a brighter, more scratch-proof polish. Pick tungsten for weight and shine, titanium for an almost-weightless feel.
