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.
A black medical-grade silicone band at 6mm or 8mm: safe in every environment where a metal ring would create a hazard. Medical-grade silicone: hypoallergenic, flexible, MRI-safe, and safe in environments where metal rings are a hazard. For buyers who work in environments where metal rings are not permitted, or who needed a ring they could wear through sport, the gym, and manual work without removing it.
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.

The Silicone Ring for Every Environment
The Kepler is a black silicone ring at 6mm or 8mm. It is the ring for buyers who work in trades, medical environments, physical jobs, or high-contact sport, and who needed something they could wear without thinking about removing it.
35 reviews from buyers who wear it through the situations that make metal rings impractical. The consistent observation: once the fit is right, the Kepler stays on and does not get in the way.
Several buyers purchased the Kepler as a second ring alongside their metal wedding band, worn for work and sport so the metal ring does not need to come off.
Silicone does not conduct electricity, will not scratch equipment, and cannot trap the pressure that makes metal rings dangerous in physical work environments. It is flexible enough to give way safely under impact.
Newman Bands offers a free size exchange if the fit is not right first time.

“I’ve been searching for some silicone wedding bands for my husband and loved the Kepler and Vigour designs. I ordered one of each in black and they 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! He could hardly wear his wedding band due to having a manual job and can now wear these bands every day without worrying and has commented on how comfortable they are. I ordered the same size as his wedding band and they fit perfectly. Thank you so much, I highly recommend!”
Helen, a UK buyer
35 reviews. Buyers who needed a ring they could wear through physical work, contact sport, and medical environments consistently find the Kepler delivers. Several note it as the ring they actually wear every day, with the metal ring kept for occasions.
You have 100 days to try it at home. If it’s not right for any reason, return it free.
