What Is PVD Jewelry? Your No-Nonsense Guide to Switzerland's Most Durable Gold Finish
Share
There is a moment every woman knows. She is getting ready — for the gym, for the pool, for a long day that will move through several versions of itself before it ends. And she stands in front of her jewelry, doing the calculation she has done a hundred times before: which pieces can survive today, and which ones have to stay behind?
PVD jewelry Switzerland was built to end that calculation permanently.
If you have been hearing the term PVD and wondering what it actually means — whether it is genuinely different from regular gold plating, and whether it is worth the investment — this guide is for you. No technical overwhelm. Just the truth, told beautifully.
Gold Plating vs. PVD Coating — What's Actually Happening to Your Jewelry?
Think of traditional gold plating like painting a wall with a single coat of emulsion. It looks gorgeous on day one. By week three, it chips at the edges. By month six, the base shows through.
Gold plating works by submerging the base metal in a liquid bath containing dissolved gold ions. An electrical current causes gold particles to bond to the surface. The result is a thin, soft layer of gold — typically between 0.5 and 2.5 microns — that sits on top of the metal rather than bonding deeply into it. It looks identical to solid gold. But it behaves very differently under pressure, water, sweat, and time.
PVD — Physical Vapor Deposition — is something else entirely.
In a PVD process, the base metal is placed inside a sealed vacuum chamber. Pure gold is then vaporised at extreme temperatures and bombarded onto the surface of the metal at a molecular level. The gold does not simply coat the surface — it becomes part of it, bonding at a depth and density that conventional plating cannot approach.
The result is a finish that is 5 to 10 times harder than standard gold plating, dramatically more scratch-resistant, and resistant to the elements that destroy conventional jewelry: chlorine, saltwater, sweat, UV exposure, and daily friction.
This is the technology inside every Raline Bergemann piece. And it is why your gold still looks like gold after a hundred lake swims.
Why 18K Gold PVD Is the Only Gold Worth Wearing to the Gym, Pool, and Concert
Not all PVD jewelry is equal. The quality of the outcome depends on two things: the purity of the gold used in the vaporisation process, and the quality of the base metal beneath it.
At Raline Bergemann, the gold is 18-karat — the sweet spot between richness of colour and structural durability. Pure 24-karat gold is too soft for active wear. 9-karat gold lacks the warmth and depth that makes gold worth wearing. 18K gives you the luminous, unmistakable colour of real gold with the resilience to survive real life.
The base metal beneath it is 316L surgical-grade stainless steel — the same material used in medical implants and surgical instruments. It is fully hypoallergenic, non-oxidising, and one of the most stable materials in the world. It does not rust. It does not react with skin. It does not degrade in water.
Together — 18K gold PVD on 316L surgical steel — they create a piece of jewelry that is genuinely, scientifically, provably waterproof. Not “shower-safe.” Not “water-resistant.” Waterproof. The kind you wear into Zürichsee on a Tuesday and forget you are wearing it at all.
And that forgetting — that seamless presence — is precisely what the Daily Glow Collection was designed to give you.
The Science Behind “Waterproof” — And Why Cheap Jewelry Lies to You
The word “waterproof” is one of the most abused terms in the jewelry industry.
Walk into any fast fashion accessory store and you will find necklaces labelled “water-resistant” or “tarnish-free” that begin discolouring within weeks of regular wear. This is not an accident — it is a consequence of thin plating, low-grade base metals, and no accountability. The language is chosen to suggest durability without legally committing to it.
Here is what genuine waterproof actually requires:
A base metal that does not oxidise or corrode — 316L stainless steel meets this standard. A coating thick and hard enough to resist chlorine, salt, and the acid in human sweat — PVD at the correct micron depth meets this standard. EU certification confirming the absence of harmful substances — REACH regulation provides this framework, and every Raline Bergemann piece complies with it.
When a brand can confirm all three — base metal, coating quality, and third-party certification — the word waterproof is earned. That is the standard we hold ourselves to, and it is why the Raline Bergemann brand story begins with a promise rather than a disclaimer.
How to Spot Real PVD Quality — A Checklist
Before you invest in any PVD jewelry, ask these questions:
What is the base metal? It should be 316L surgical-grade stainless steel or titanium. If the brand does not specify, that is your answer.
What karat is the PVD gold? 18K is the standard for premium waterproof jewelry. Lower karats produce a paler, less saturated finish that dulls faster.
Is it EU certified? REACH and RoHS certification confirms the piece is free from nickel, lead, cadmium, and other harmful substances. This is non-negotiable for sensitive skin.
Does the brand offer a guarantee? A brand that stands behind its PVD process will back it with time. Raline Bergemann offers the Blue Fire 2-Year Guarantee — because we already know the jewelry will outlast it.
Does the finish feel smooth and even? Real PVD has a precision finish. Uneven texture, visible bubbles, or a plasticky sheen are signs of inferior coating.
Raline Bergemann’s 18K PVD — EU-Certified and Built for Your Intentional Days
At Raline Bergemann, we did not choose PVD technology because it was trending. We chose it because it was the only honest answer to a question our founder refused to stop asking: why should a woman ever have to choose between her jewelry and her life?
Whether your day holds a morning spin class, a lakeside lunch, an afternoon meeting, or a concert under the stars — your gold should be present for all of it. Not as a passive accessory, but as an active reminder. A glance at your wrist between emails. A flash of gold in the gym mirror. That micro-moment of redirected intention — from the obligatory to the precious — is what we call your Blue Fire.
We explored what this means in depth in our first two posts: why Raline Bergemann makes waterproof jewelry in Switzerland and the founder’s story that started it all. If you have not read them, they are worth the quiet ten minutes.
Every Raline Bergemann piece is nickel-free, lead-free, cadmium-free, REACH and RoHS compliant, and built with 18K PVD on 316L surgical steel. And in 2026, every purchase contributes a portion of net profit to Krebsforschung Schweiz — because the courage to live fully and the courage to care for others are the same fire.

Frequently Asked Questions
What is PVD jewelry and is it real gold?
PVD jewelry uses a process called Physical Vapor Deposition to bond real gold — at Raline Bergemann, 18-karat gold — to a base metal at a molecular level inside a vacuum chamber. It is genuine gold, applied with a precision and permanence that traditional gold plating cannot match. PVD jewelry is waterproof, tarnish-resistant, and dramatically more durable than conventionally plated pieces.
How long does PVD gold jewelry last compared to gold plating?
High-quality PVD gold jewelry lasts 5 to 10 times longer than standard gold plating under equivalent daily wear conditions. With proper care — and even with regular exposure to water, sweat, and daily activity — 18K PVD on 316L stainless steel maintains its finish for years. Raline Bergemann backs this with a Blue Fire 2-Year Guarantee on every piece.
Is PVD jewelry safe for sensitive skin?
Yes. 18K PVD on 316L surgical-grade stainless steel is fully hypoallergenic, nickel-free, lead-free, and cadmium-free. Every Raline Bergemann piece is certified compliant with EU REACH and RoHS regulations — the most rigorous jewelry safety standards in the world — making it safe for even the most reactive skin types.
Can I wear PVD jewelry in the pool and the gym?
Absolutely. Unlike gold plating, which degrades rapidly when exposed to chlorine, salt, and sweat, PVD coating is chemically resistant and structurally stable in all of these environments. Raline Bergemann jewelry is designed specifically for the active Swiss woman — worn in, not left behind.
