A polished silver tungsten band at 8mm with a cogwheel-patterned blue groove inlaid through the centre of the band.

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.

Cogwheel Pattern, Blue in Silver
The Cogwheel is a silver tungsten band with a blue groove through the centre that carries a cogwheel edge pattern rather than a smooth edge. The serrated profile of the groove gives the ring a mechanical, engineered character.
At 38 reviews it is one of the more consistently reviewed patterned rings in the range. Buyers who work in engineering, construction, or precision roles tend to choose it because the pattern resonates with them.
The Cogwheel suits buyers who looked at every smooth-groove blue and silver ring and wanted the one with a detail that connects to something specific.
The cogwheel groove pattern on the Cogwheel is set into a tungsten carbide base. Tungsten is hard enough to hold the defined edges of the pattern through daily wear, where a softer metal would gradually round the serration.
Tungsten cannot be resized, but Newman Bands offers a free size exchange if the fit is not right first time.
“I had an accident involving my wedding ring a good few years back, leaving me needing surgery. The scar tissue where my ring sits gave me irritation when I tried to wear my repaired wedding ring. After years of not wearing a ring I looked into alternatives, including tattoos, but decided on a “chunky” ring, one that wouldn’t dig in. I couldnt have chosen better, this ring is perfect in design, no issues at all, and the cog design has attracted quite a few comments, all positive. The sizing was perfect and I’m confident the tungsten will help protect my finger from future incidents, not buckle and distort. I’m intrigued how long the inlaid design will remain but, should its lustre fade, I’ll pick up another one. In all honesty I like it so much I may pick others just to have alternatives.”
