Waterproof Jewellery Explained.

Let's be honest: technically, all jewellery is waterproof, because it doesnt dispose in water. Yet waterproof jewellery has become a common term in the jewellery industry, and for good reason.

When we talk about waterproof jewellery, we generally mean pieces you can wear while swimming, surfing or showering without the metal turning black, green, blue or developing unwanted discolouration.

But there's another important part to the story: waterproof jewellery is also about how well the gold finish holds up over time.

You might have seen gold-plated jewellery lose its colour after just a few wears. That's where the quality of the plating makes a real difference. At Osealina, we use high-quality PVD gold plating over recycled marine-grade stainless steel, chosen for its durability and resistance to everyday wear.

If you’re looking for waterproof jewellery in Australia, you probably want pieces that can keep up with your lifestyle. Jewellery you can wear for morning ocean dips, long surf sessions, beach days and spontaneous adventures without constantly taking it off. 

Can You Swim, Surf and Shower in It?

At Osealina, we believe jewellery should fit into your life, not the other way around. Designed in Byron Bay, Australia, our jewellery is made for women who want to feel in their element, wherever the day takes them. Here’s everything you need to know about waterproof jewellery, the materials we use and how to keep your favourite pieces looking beautiful.

What Is Waterproof Jewellery?

Waterproof jewellery is designed to withstand contact with water without rusting, corroding or losing its appearance under normal conditions. However, not all jewellery marketed as waterproof is made the same way.

The durability of a piece depends on its base material, the type and quality of its plating, its construction and how it is cared for over time.

Traditional gold-plated jewellery often has a quite thin layer of gold over a base metal that may be more susceptible to corrosion or discolouration. When exposed to moisture, sweat and everyday products, the finish can wear down, revealing the metal underneath. If this metal oxidates, you get the ugly look.

Waterproof jewellery uses materials selected for their resistance to water and corrosion. At Osealina, we use recycled marine-grade stainless steel with gold PVD plating to create jewellery designed for everyday wear, including adventures around the ocean.

The result? Jewellery that combines the look of gold with the practicality you need for an active, coastal lifestyle.

What Is Osealina Jewellery Made Of?

The secret to durable, waterproof gold jewellery starts with the materials.

Marine-grade stainless steel

Our jewellery is made using recycled marine-grade stainless steel, a material chosen for its strength and resistance to corrosion.

Unlike many base metals used in conventional jewellery, a high quality stainless steel naturally forms a protective layer that helps prevent rust and corrosion. This makes it a practical choice for jewellery exposed to moisture, sweat and everyday wear. Watch out, STAINLESS STEEL DOES NOT EQUAL STAINLESS STEEL. There are many different qualities on the market!

Using high quality and recycled stainless steel also supports our approach to more considered jewellery design. We want to create pieces you can reach for again and again, rather than jewellery that spends most of its time sitting in a jewellery box.

Gold PVD plating

So, how do we achieve that beautiful gold finish?

PVD stands for Physical Vapour Deposition. It is a process that deposits a thin coating onto a material under vacuum conditions, creating a durable finish that adheres well to the surface.

Compared with many traditional gold-plating methods, PVD coatings can offer improved resistance to everyday wear and abrasion. Combined with stainless steel, this helps create jewellery that is better suited to an active lifestyle.

Our gold-finished designs use PVD plating over marine-grade stainless steel, giving you the warm look of gold without needing solid gold jewellery.

Can You Swim in Waterproof Jewellery?

Yes, Osealina jewellery is designed to be worn while swimming. Whether you're heading for a refreshing ocean dip, spending the afternoon at the beach or jumping into the pool, our pieces are made with water-loving adventures in mind.

Here is what to know about different environments.

Salt water and the ocean

Salt water is one of the biggest considerations when choosing jewellery for an Australian coastal lifestyle. Salt deposits can accumulate on jewellery, and prolonged exposure without rinsing may contribute to surface deterioration over time.

Stainless steel is corrosion-resistant, making it a suitable material for jewellery designed around ocean adventures. Our PVD gold finish adds another layer of durability for everyday wear.

You can wear your Osealina pieces for ocean swims and beach days. After swimming in the sea, simply rinse them with fresh water and dry them thoroughly. This helps remove salt residue and keeps your jewellery looking its best.

Whether you're surfing at The Pass, enjoying a morning dip at Wategos or travelling somewhere tropical, your jewellery is made to come along for the ride.

Chlorine and swimming pools

Chlorinated water can be harsher on jewellery than freshwater. Repeated or prolonged exposure to chlorine may affect metal surfaces and contribute to the gradual deterioration of gold plating.

Although Osealina jewellery is designed to handle everyday water exposure, we recommend rinsing your pieces after swimming in a chlorinated pool. If you swim regularly, removing your jewellery before extended pool sessions is a sensible extra precaution to help preserve its finish.

Showers and everyday water exposure

Can you shower in waterproof jewellery? Yes, showering is generally fine for our stainless steel and PVD-plated pieces. 

However, CHEMICALS in soap, shampoo, conditioner and other shower products can leave residue on jewellery. Over time, frequent exposure to these products may affect the gold finish, resulting in a lost shine and potential base material appearing.

For the longest-lasting finish, we recommend removing your jewellery before long showers or washing your hair with shampoo. 

The idea isn't to make caring for your jewellery complicated. It's simply about understanding that water resistance doesn't mean immunity to every product or condition.

Is Waterproof Gold Jewellery Really Tarnish-Free?

One of the most common questions we hear is whether waterproof gold jewellery will tarnish at some point.

High quality Stainless steel is naturally resistant to rust and corrosion, while PVD plating is designed to provide the most durable surface finish. Together, these materials help our jewellery maintain its appearance through everyday wear.

However, there is an important distinction between tarnish-resistant and impossible to change. Some brands claim a colour warranty for life, well - we say lets keep it honest=)

What About Sunscreen, Sweat and Perfume?

Living in Australia often means sunshine, sunscreen, salty skin and plenty of time outdoors. But these everyday essentials can affect jewellery finishes over time.

Here's how to protect your pieces:

• Sunscreen: Apply sunscreen before putting on your jewellery. Allow it to absorb into your skin, and avoid leaving thick residue on your pieces. Also here, it wont happen if you just do it once every now and then. all depends on the frequency. 

• Sweat: Sweat contains salts and other substances that can accumulate on jewellery. Rinse your pieces after workouts or particularly sweaty days.

• Perfume and body products: Apply perfume, moisturiser and body oils before putting on your jewellery. Let them dry before wearing your pieces. With our natural stones, body oils will be absorbed resulting the stone to get dull over time.

• Cleaning products: Avoid repetitive direct contact with household chemicals, harsh cleaners and abrasive products.

These simple habits help reduce residue and unnecessary wear, keeping your jewellery looking beautiful for longer.

How to Care for Waterproof Jewellery

Waterproof jewellery is designed to make life easier, and caring for it shouldn't feel like a chore.

Follow these simple steps to keep your Osealina jewellery in great condition:

1. Rinse after ocean swims. Use fresh water to remove salt and sand.

2. Dry thoroughly. Gently pat your jewellery dry with a soft cloth after getting it wet.

3. Keep chemicals away. Minimise direct contact with sunscreen, perfume, chlorine and harsh cleaning products.

4. Clean gently. Use a soft, damp cloth to remove everyday residue. Avoid abrasive materials that could scratch the finish.

5. Be mindful of friction. Repeated rubbing against other jewellery, hard surfaces or equipment can gradually wear the gold coating.

You don't need special storage conditions or an elaborate cleaning routine. A little attention after your adventures is usually enough.
