We are fully committed to creating and providing the best standard of jewellery, which is why we offer a Lifetime ARMR Guarantee for all purchases of jewellery.

If your jewellery develops a craftsmanship defect, we’ll replace it once - whenever you need it, for life.

This Guarantee is voided under any user damage issues (scratches and accidental breakage). ARMR Guarantee does not cover lost or stolen items.

CARE

Our jewellery is 100% sweat and waterproof, heat resistant, 10x stronger than gold-plated jewellery and perfume/lotion safe.

We use the highest grade stainless steel which is a highly durable, 100% recyclable metal. Its properties mean that it does not oxidise or rust, is hypoallergenic, doesn't scratch easily and will not tarnish.

At ARMR, sustainability is approached through material, craftsmanship, longevity and responsible sourcing. We believe jewellery should be created to last, both in quality and design, rather than follow fast-moving trends.

That's why we chose premium grade stainless steel as the base metal for our pieces. Premium grade stainless steel is an incredible metal that is super durable but also 100% recyclable.

We're working hard to ensure all of our packaging is as sustainable as possible too. This is an ongoing process and is being reviewed all the time.

We believe in creating modern symbols of resilience. Pieces designed to be worn, loved and kept for years to come.

made to be worn everyday

Stillness. Strength. Shadow.

There’s power in the quiet. In the calm before the storm. In the moments when you hold your ground—not because you’re loud, but because you’re solid. The Sentinel Pendant is forged from that spirit.

Featuring a striking rectangular slab of deep black onyx, this pendant doesn’t ask for attention—it commands it. For centuries, onyx has been worn as a stone of grounding and protection, carried by warriors and leaders to keep their focus sharp and their feet steady. Its dark surface is a mirror to your inner resolve—strong, measured, and unwavering.

The pendant’s bold shape speaks of balance and boundaries. It doesn’t bend to trends. It doesn’t pretend to be anything it’s not. It stands for what you stand for: quiet confidence, heritage, and the strength to move forward no matter the weight you carry.

Suspended from a refined link chain, the piece is made to move with you—through city streets, early mornings, late nights, and everything in between. It’s tarnish-free, water and heat-resistant, and built for everyday wear.

Worn as armour. Carried as truth. The Sentinel is a reminder: sometimes the most powerful thing you can do... is stand still.

What's this piece made of?

Premium Grade Stainless Steel

Built to Last

Our jewellery’s made from premium grade stainless steel, the good stuff. It’s tough, corrosion-resistant, and shrugs off everyday wear like it’s nothing. No tarnishing, no fading. Just solid pieces that stay sharp over time.

No Itching, No Green Skin

Got sensitive skin? No worries. Our jewellery’s hypoallergenic, so you can wear it all day, every day, with zero irritation. No rashes, no reactions, just clean, comfortable wear.

Looks Good, Costs Less

Premium shouldn’t mean pricey. Stainless steel gives you style, strength, and staying power, without the cost of precious metals. That means great-looking jewellery that won’t rinse your wallet.

Necklace & Chain Length Guide

Finding the right necklace length can make all the difference.

Whether you prefer a close fit that sits at the collarbone or something longer that layers easily over a tee, our guide helps you choose the length that suits your style and build.

From 16"/40cm to 25"/65cm, we’ve broken down what each size looks like when worn, so you can find the fit that feels most like you.

FREQUENTLY ASKED QUESTIONS

WHAT IS YOUR JEWELLERY MADE FROM?

Our jewellery is made from highly polished premium grade stainless steel. Our gold pieces use real 18K gold infused coating - not plated. Our pieces are incredibly hard wearing and will not chip like gold plated jewellery.

DO I NEED TO TAKE SPECIAL CARE OF MY JEWELLERY?

Not really. Our pieces are super durable, waterproof and sweat-proof. We wear our ARMR pieces at the gym, hiking, swimming, showering - all sorts. You can clean them with a lint cloth to rebuff them and keep their shine but other than that, you're good.

Obviously, don't go nuts and start scraping your jewellery across rocks and hitting it with a hammer. If you keep to normal day to day wear then it'll be fine.

WILL IT TURN MY SKIN GREEN?

Our pieces are made with premium grade stainless steel which is classed as hypoallergenic (meaning it's more friendly on your skin) and means there is extremely low risk to any allergic reaction.

Every one is different, so we cannot guarantee you won't have a reaction, but from what we know about the material we use the risk is incredibly small.

Our pieces are suitable for everyday use in every situation. Strong, durable, tarnish resistant and waterproof, our items are affordable and suitable in all places.
