Why Choose Silicone Rings
Silicone is safe for every situation a metal ring is not: the gym, swimming, contact sports, manual work, and medical environments. It won't conduct electricity, won't scratch tools or equipment, and won't trap the kind of pressure that makes metal rings a hazard on the job.
Medical-grade silicone — no metal, no conductivity, no risk. Safe for electricians, mechanics, surgeons, and anyone who can't wear metal on the job.
Hypoallergenic and skin-safe. No nickel, no reactions, no redness. If metal rings have caused problems before, silicone won't.
Shower, swim, gym, sea — silicone doesn't corrode, rust or react. Flexible enough to move with your hand, tough enough for daily wear.
Every ring arrives in a presentation gift box — no extra packaging needed. Ready to give exactly as it arrives.
Matte black silicone with a smooth domed profile. Lightweight, flexible, and designed to be worn where metal rings can’t go — at work, in the gym, travelling, or anywhere you need a ring that moves with you. Most buyers pick the Kepler as a safe alternative to their wedding band for manual jobs, or as an everyday ring for an active lifestyle.
Silicone is hypoallergenic, non-conductive, and engineered to break away under dangerous force — so it protects the finger instead of trapping it. You’ll barely feel it on your hand. 55+ five-star reviews from buyers who wear it daily. Comfort-fit. 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?
Not quite the right fit? No problem. Silicone rings are flexible, but if the size isn’t perfect, we offer free exchanges or refunds — no questions asked. You have 100 days to return it for any reason.
Not sure of your size? Select “I don’t know my ring size” from the dropdown and we’ll send you a free ring sizer first.
THE DETAILS
Silicone rings are engineered with a breakaway point — strong enough for daily wear, designed to snap under dangerous force. If the ring catches on machinery, a climbing hold, or a loaded barbell, it breaks cleanly instead of trapping your finger. Niall from Westhill, a joiner, switched from his platinum ring for exactly this reason: “The silicone rings are perfect for what I need.”
Silicone weighs almost nothing on the finger. Buyers consistently describe it as something they stop noticing within minutes. Tegan from Dartford bought it for her husband for everyday and travel use: “He said it’s unbelievably comfortable, it looks great on, removes easily to wash hands. Well worth it.”
The Kepler has a smooth domed profile in matte black. It sits cleanly on the finger and reads as a deliberate choice, not a temporary stand-in. Charlie from London wears it alongside his tungsten ring: “The two look almost identical at a glance.” Faye from Neath said her partner was surprised — “He thought it would feel flimsy like elastic but he said it feels sturdy.”
Every Kepler arrives in a presentation box. Not sure of their size? We’ll send a free ring sizer first. Wrong size? Return it free and we’ll exchange it the same day it arrives. Chantelle from Bedford ordered one as a gift: “Absolutely fantastic company. Was even treated to an extra ring. Great quality, well packaged with added details. Incredible communication and super fast delivery.”

Who This Ring Is For
The Kepler is bought by people who need a ring they can wear everywhere — especially where metal isn’t safe or isn’t practical. Joiners, carpenters, engineers, gym-goers, rugby players, rock climbers. Buyers who work with machinery and can’t risk a metal ring catching. Partners buying a safe alternative so their husband can still wear a ring at work.
Ross from Colchester works in a hands-on workplace where metal jewellery isn’t permitted. Emily from London bought one because her husband works with machines and had to keep removing his wedding ring. Helen from Harlow’s husband has a manual job and couldn’t wear his wedding band — now he wears the Kepler every day.
The reason is consistent: they want to wear a ring, and silicone lets them do it safely.
A smooth, domed band in matte black. No edges, no ridges, no pattern — just a clean curve that sits flat against the finger. The surface is soft to the touch and flexible enough to stretch over the knuckle and settle into position. It doesn’t catch on gloves, tools, or equipment.
Nathaniel from Walton-on-Thames described the fit: “Fits perfectly and has some stretch room so it’s not a struggle to take off over the knuckle.”
“Comfortable, durable, and looks great. Highly recommend for anyone looking for a stylish yet practical ring.” — Tom Iddon, Ayr
Why Silicone Works
Silicone is hypoallergenic, waterproof, and non-conductive. It won’t react with skin, rust, tarnish, or conduct electricity. For anyone who works around machinery, electrical hazards, or heavy equipment, that matters.
The key safety feature is the breakaway design. Under dangerous pulling force — the kind that would deglove a finger trapped in a metal ring — the silicone snaps cleanly. It’s strong enough for daily wear and designed to give way when it needs to.
Silicone can’t be resized in the traditional sense, but it has natural stretch that provides flexibility in fit. If the size isn’t right, return it free and we’ll exchange it the same day it arrives.
How it Compares
Buyers consistently describe the Kepler as better quality than they expected. The domed profile and matte finish look deliberate and well-made — not like a cheap rubber band. Charlie from London bought it alongside a tungsten ring and said the two look almost identical at a glance.
The most common comparison buyers make is value for what you get. Ewan from Bridgend summed it up: “Durable and excellent value for money.” For a ring that protects your finger, replaces your wedding band at work, and arrives in a presentation box, buyers consistently say it delivers far more than they expected.

“I’ve been searching for some silicone wedding bands for my husband and loved the Kepler. I ordered one in black and it arrived the following morning. Clare also included a grey ring as a free gift which I thought was such a kind gesture. The rings are gift boxed beautifully and my husband hasn’t taken them off since.”

The most common reason buyers choose the Kepler is workplace safety. Over 15 of the 57 five-star reviews mention wearing it specifically because a metal ring isn’t safe or allowed at work — joiners, carpenters, engineers, and anyone working with machinery. Charlie Knight from London wears his alongside a Jet tungsten ring, swapping to the Kepler when he’s on site. Niall Clouston from Westhill switched from platinum for safety reasons.
“My partner was surprised — he thought it would feel flimsy like elastic but he said it feels sturdy and has tried it out in the gym several times with no issues.”
Faye Priestley, Neath
“I ordered a silicone ring for my husband because he works with a lot of machines so has to take his wedding ring off. This product is perfect — he doesn’t have to take his ring off now.”
Emily Foulds, London
Comfort is the second most repeated theme — buyers describe a ring they forget they’re wearing. Gym-goers, rugby players, rock climbers, and musicians all choose the Kepler when their metal band would get in the way. Kush Radia from Enfield Town needed a size exchange and received two extra colours included free of charge. All 57 verified buyers gave it five stars.
