Engrave Your Ring
Add a date, initials or message, laser engraved in-house and dispatched the same day. Most engravers add days to delivery. We don't.
Tungsten carbide rates 9 on the Mohs hardness scale — just below diamond. Only a diamond can mark it.
Tungsten don't react with air, water or skin — ever. Our colours outlast precious metal equivalents.
Built for long-term wear — retains its shape and finish even with daily use.
Every ring arrives in a presentation gift box — no extra packaging needed. Ready to give exactly as it arrives.
A black tungsten band at 6mm or 8mm with a rainbow groove inlaid through the surface. Tungsten carbide is one of the hardest metals used in jewellery: it won’t bend, deform, or tarnish. A men’s wedding ring for buyers who chose the rainbow groove as the detail that makes their ring specific: engravable, dispatched same day.
What makes this ring worth it?
Walk into a jeweller and you’ll find versions of our rings for 3–4 times the price. The difference isn’t the ring — it’s the overheads. We work directly with the craftspeople who make them and carry the stock ourselves, which is how we can sell a ring that genuinely lasts for a fraction of high street prices.
Traditional gold and silver scratch, bend and lose their shine. That doesn’t happen here. We use a high end process called PVD plating which is the same process used on high end watches to keep your ring looking great.
Why buy from Newman Bands?
We’re based in Horsham and dispatch the same day for orders before 5pm (11am Saturday). That includes engraved rings — we hold stock and engrave on site, which is why we can still get it to you in 1–2 days. Most online ring sellers take 2 weeks or more.
We’ve fulfilled over 100,000 orders since 2019 and hold over 10,000 five-star reviews across Trustpilot and Reviews.io. Any questions before you buy — contact us directly. No chatbots, no outsourced support. We handle it ourselves.
What if it doesn't fit?
Tungsten and titanium can’t be resized, so we offer free exchanges or refunds on unengraved rings — no questions asked. If you want a refund or an exchange, you have 100 days to return it free for any reason.

Black Tungsten, Rainbow Groove
The Unity is a black tungsten band with a rainbow PVD groove through the surface. The rainbow groove shifts colour depending on the light and viewing angle.
At 23 reviews buyers who chose the rainbow groove consistently find the colour shift is more vivid in person than the product images can show.
The full black base gives the rainbow groove the darkest possible background, which intensifies the colour shift.
The black and rainbow surfaces on the Unity are PVD finishes on tungsten carbide. Tungsten holds both at the groove boundary through daily wear.
Tungsten cannot be resized, but Newman Bands offers a free size exchange if the fit is not right first time.
“I absolutely loved the ring and so did my fiancé. He wanted something that didn’t look like a wedding ring, but that showed he was engaged. This was the perfect mix between being tough and durable, but also a lovely colour with the rainbow bit in for fun.”
Liz, a UK buyer
23 reviews. Buyers who chose the rainbow groove find it is more vivid and distinctive in person. The colour shift is more pronounced against the full black base, and the finish holds through daily wear.
You have 100 days to try it at home. If it’s not right for any reason, return it free.
