Black tungsten with an iridescent rainbow groove that shifts colour in the light. Available in 6mm and 8mm. The groove catches greens, purples, blues and golds depending on the angle — bold enough to notice, but set into a matte black band that keeps it grounded. The Unity is one of the most gifted rings in our range. Partners buy it for birthdays, engagements, and weddings. Buyers who choose it for themselves tend to want something with personality — a ring that stands out without looking like costume jewellery. Rated five stars by all 30+ verified buyers so far.
Tungsten carbide rates 9 on the Mohs hardness scale — one below diamond. The black finish and rainbow groove are both bonded using PVD coating, the same vapour deposition process used on luxury watches. It won’t scratch from daily wear, won’t tarnish, and won’t react with skin. The 6mm suits anyone who wants a slimmer profile; the 8mm carries more presence on the hand. Comfort-fit interior. Engravable. Dispatched today.
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?

THE DETAILS
Tungsten carbide sits at 9 on the Mohs hardness scale — one below diamond. The black finish and the rainbow groove are both applied using PVD coating, bonded at a molecular level rather than plated on top. Whether you choose 6mm or 8mm, the same finish and the same durability. Adrian, a photographer from London, wears the Unity on his dominant hand daily: “Exposed to more potential bumps and scrapes than normal — it still looks brand new without a scratch on it.”
Tungsten carbide is comparable in density to 18K gold. The 8mm sits heavier on the hand; the 6mm has the same density in a slimmer profile. You’ll notice the weight the first time you pick it up — it feels like proper jewellery, not a lightweight alternative. Lorraine from Beverley bought one as a Christmas gift and noticed it immediately: “Heavier than what we thought it would be — an excellent ring and very good value.”
The central rainbow groove shifts between greens, purples, blues and golds depending on the angle and the light. It’s iridescent, not painted — the colour is created through the PVD process, so it won’t wear off or fade. Set into a matte black tungsten band, it gives the Unity a look that buyers describe as different from anything else they’ve seen. Stephen from Hyde: “Absolutely loved the colours, very vibrant and stands out.”
Every ring arrives in a presentation box. Add a date, name, or message with laser engraving done in-house. Both widths are engravable and dispatched the same day. Charlie from Newcastle upon Tyne ordered the Unity as an anniversary gift: “It arrived really quickly and looks exactly as described and pictured. The quality is lovely, and my boyfriend absolutely loves it.”

Who This Ring Is For
The Unity is bought as a wedding band, an engagement ring, an anniversary gift, and as a statement piece for men who want colour without going loud. It comes in two widths — 6mm for those who prefer a slimmer look and 8mm for anyone who wants more weight and coverage on the finger. Charlotte from Stockport bought it for a partner who had never owned a ring before. Mandi used it for a leap year proposal. Jonathan from Burnley chose it for his January wedding. Tim from the UK bought it as a ruby wedding anniversary gift for a husband who never had a ring the first time around.
The occasions vary, but the common thread is the same: something bold, well-made, and unlike a standard band.
A black tungsten band with an iridescent rainbow groove running through the centre. The groove shifts colour depending on the angle and light — greens, purples, blues and golds appear and disappear as you move your hand. The sections either side of the groove are matte black, and the overall effect is a ring that looks different every time you glance at it. Available in 6mm and 8mm, so you can choose the proportion that suits your hand.
Liz from Newport chose the Unity for her fiancé specifically because of that balance: “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 Feldwick, Newport
Why Tungsten Lasts
Tungsten carbide is one of the hardest materials used in jewellery — 9 on the Mohs scale, one step below diamond. It won’t scratch from everyday contact, won’t bend under pressure, and won’t tarnish from moisture or skin. Both the 6mm and 8mm use the same tungsten carbide base with PVD coating — a vapour deposition process that bonds colour at a molecular level rather than plating it on top. The rainbow groove is created through the same PVD process, so the iridescence is permanent.
Tungsten can’t be resized. If the fit isn’t right, return it free and we’ll exchange it the same day it arrives.
How it Compares
Buyers consistently describe the Unity as looking and feeling far more expensive than they expected. The weight of the tungsten and the iridescent finish give it the presence of a ring from a specialist jeweller. Simon from Birkenhead: “The ring was a great cost for a great item — it’s nicely weighted and perfectly fits the description.”
A rainbow-grooved tungsten ring from a high-street jeweller or specialist brand typically costs several times what you’d pay here — and often uses the same tungsten carbide base. The material is the same. The PVD process is the same. The difference is the markup.
Buying This as a Gift?
The presentation box does the work for you — no wrapping needed. Add a laser engraving and it becomes personal. We engrave in-house and post the same day. If you’re not sure which width they’d prefer, the 8mm is the more popular choice — but we exchange free if they’d rather switch to the 6mm.
The Unity is one of our most gifted rings. Many buyers choose it specifically because the rainbow groove makes it feel personal and distinctive — it doesn’t look like every other ring in a jeweller’s window.
“My partner hasn’t ever owned a ring so I was nervous. However, I have given it to him early and we both absolutely love it.”
— Charlotte McHugh, Stockport

Thirty-five verified reviews, every one five stars. The iridescent rainbow groove is the first thing buyers mention — it shifts between greens, purples, blues, and golds depending on the light. The PVD coating is bonded into the surface, not painted on, so it holds. Adrian from London wears it daily as a photographer on his dominant hand and reports no scratches.
“I surprised him with a leap year proposal — he said yes thankfully.”
Mandi Gornall, United States
The Unity is one of Newman Bands’ most gifted rings — partners buy it for engagements, weddings, anniversaries, and birthdays. The rainbow groove makes it feel personal and distinctive. Buyers also mention the satisfying weight of the tungsten, with several noting it felt heavier than expected, which they read as quality. Fast delivery and responsive service come up repeatedly across reviews.
