You asked us for jewelry you never have to think twice about – pieces that go from Pilates to dinner without a single change. So, we created our first-ever water-resistant collection. Crafted from 18k gold or platinum, using ultra-durable PVD plating on 316L stainless steel. It's hypoallergenic, sweat-proof, and built with a self-repairing layer that keeps tarnish out. Jewelry designed for real life.

Made for Every Day 

You wanted jewelry that could keep up with you, and we listened. 

• Gym – sweat-proof, so it moves when you do.
• Shower –water-resistant enough to skip the morning ritual of taking it off and putting it back on.
• Commute – through rain or sunshine, it stays shining.
• Office – polished enough for meetings, low-maintenance enough that you forget you’re wearing it.
• Travel – long-haul flights, no jewelry box required.
• Beach – designed to go with you anywhere (and not be shy of SPF).
• Everyday layering — stack it, mix it, forget about it.

We wanted to design pieces that would sit seamlessly alongside your existing Missoma favorites, so you can mix, match and layer without a second thought. 

The Benefits, Properly Explained 

Water-resistant. From the pool to Pilates, these pieces will go with you everywhere. 

Sweat-proof. Designed for workouts, heatwaves, hot commutes, and anything else thrown at it. 

Hypoallergenic. 316L stainless steel is naturally low-reactive, making these pieces comfortable for even the most sensitive skin. 

Anti-tarnish. The 316L stainless steel base carries a self-repairing layer that actively keeps tarnish out. Ultra-durable. This is jewelry designed to be worn constantly. No need to save it for best. 

Quality tested. Every piece goes through rigorous wear-testing before it reaches you. 

So, What Does Water-Resistant Jewelry Actually Mean?   

Behind the simplicity of an everyday chain or a pair of hoops is months of sourcing, testing and refinement. 

The foundation is 316L stainless steel – a surgical-grade metal prized for its strength, corrosion resistance and naturally low-reactive properties, which is what makes it comfortable for sensitive skin. 

Onto that, we bond 18k gold or platinum using PVD (Physical Vapour Deposition) – an advanced plating process that fuses the precious metal finish to the stainless steel base far more durably than traditional plating methods. The result includes a self-repairing layer that works to keep tarnish out, rather than simply slowing it down. 

We only work with Responsible Jewellery Council audited factories that we've personally visited and vetted ourselves.

Is Water-Resistant Jewelry Actually Waterproof? 

One of the questions we hear most: is waterproof jewelry even real? There's no official industry definition for "waterproof jewelry," which is why we use the term water-resistant – in practice, the two are often used interchangeably. 

Our honest answer: no jewelry is completely indestructible forever. But these pieces, built on 316L stainless steel with 18k gold or platinum PVD plating, are specifically engineered to withstand water, sweat, heat and everyday wear. 

Why 316L Stainless Steel? 
Stainless steel lets us build water-resistant essentials that affordable, while keeping the elevated finish, craftsmanship and design details that define our jewelry. It's also what makes these pieces naturally hypoallergenic. The result: foundational pieces designed to become your everyday uniform. The chain you’ll never take off, the hoops you’ll reach for every morning, or the bracelet stack that finishes every outfit.
