AnchorCert Certified Hypoallergenic Rings

Skin-safe, irritation-free, and scientifically certified – because your ring shouldn’t come with a rash.

You shouldn’t have to choose between style and skin safety. That’s why we’ve had a huge chunk of our most popular rings tested at the Birmingham Assay Office—and they passed with flying colours. Our AnchorCert Pro Certified rings are now officially classed as hypoallergenic, meaning they’re safe for sensitive skin, nickel-safe, and ready for real life. No itching. No redness. No regrets.

From Titanium to Tantalum, Damascus Steel to Black Zirconium - this collection brings together our strongest styles in materials proven to be kind to your skin. So if you’ve ever reacted to jewellery before (or you just want peace of mind), these rings are the real deal. Tough, stylish, and lab-approved.

What does AnchorCert Certified mean?

Developed by the experts at the Birmingham Assay Office, the AnchorCert Pro test doesn’t mess about. It screens jewellery for nickel, cobalt, chromium, and other metals known to cause irritation or allergic reactions. Each ring is tested using artificial sweat (yes, that’s a thing) and surface scanning to simulate how it’ll behave on your skin.

Only pieces that pass the entire testing process get the official “Hypoallergenic” certification. We’re proud to say these rings did just that—and now you’ll find that little logo on our pages like a badge of honour.

Strong metals. Sensitive skin. No compromise.

These rings aren’t just certified—they’re built to last. Whether it’s Titanium that’s ultra-light and comfy, Cobalt with its sleek, high-shine finish, or Black Zirconium with a moody matte look, each material in this collection brings something different to the table—except skin irritation. That bit’s been removed entirely.

Perfect for everyday wear, active lives, and commitment that lasts a lifetime—without the uncomfortable side effects.
