If you've been shopping for jewelry lately, especially in the handmade or DTC space, you've probably noticed more and more brands talking about PVD gold plating. Maybe you've seen it on an Altru product description and thought, okay, but what does that actually mean?

I get it. Jewelry material terminology can feel like a foreign language, and a lot of brands don't make it easy to understand. So let's break it down, clearly and most importantly, honestly.

What Is 18K Gold PVD Plating?

PVD stands for Physical Vapor Deposition. It's a coating process used across a number of industries, from aerospace engineering to medical devices, and it's become increasingly popular in jewelry because of how incredibly durable and long-lasting it is compared to traditional plating methods.

Here's the simple version of how it works: in a vacuum chamber, gold particles are vaporized and then bonded directly to the surface of the metal underneath — in our case, stainless steel. This isn't a thin wash of color sitting on top of a base metal. The bond created through PVD is molecular, meaning the gold coating actually fuses to the stainless steel at a microscopic level. The result is a finish that is significantly harder, more scratch-resistant, and longer-lasting than standard electroplated jewelry.

The "18K" part refers to the gold content of the coating itself. 18-karat gold is 75% pure gold, which means the color you're seeing on an 18K PVD piece is a rich, warm gold tone — not the thin, brassy look of low-quality plating.

How Is PVD Different from Gold Plating?

Standard gold plating (the kind you'll find on a lot of fashion jewelry) uses an electroplating process where a very thin layer of gold is deposited onto a base metal. That layer can be as thin as 0.5 microns. It looks great out of the box, but it's also the reason your jewelry irritates your skin, changes color or starts to look dull after a few months of wear. The coating simply wears off and you're left with whatever mystery base metal is underneath.

Gold-filled jewelry, which is often considered a step up, uses a mechanical bonding process that applies a thicker layer of gold over a base metal core — typically brass. Gold-filled pieces are required by US law to contain at least 5% gold by weight, which gives them better durability than standard plating. For a long time, gold-filled was considered the gold standard (no pun intended) for affordable fine jewelry.

The current problem with gold-filled is that the cost of gold is at an all time high right now. So it's not very approachable or affordable for many consumers.

PVD plating, particularly on a stainless steel base, changes the equation. The hardness of the stainless steel combined with the molecular bond of the PVD coating means the finish holds up better over time, often outperforming gold-filled in everyday wear conditions. And unlike brass-core gold-filled pieces, stainless steel doesn't corrode, which matters a lot if you have sensitivity to certain metals.

(More on that below.)

Is 18K PVD Gold Jewelry Hypoallergenic?

This is one of the most common questions I see, and the answer is: for most people, yes. The reason comes down to the base metal.

Stainless steel — specifically the 316L surgical-grade stainless steel that quality PVD jewelry is made from — is widely considered hypoallergenic because it contains very low levels of nickel and, more importantly, the nickel it does contain is bound within the alloy structure rather than sitting on the surface. This makes it far less likely to trigger a reaction in people with nickel sensitivity.

The PVD coating itself adds an additional barrier between your skin and the metal, which further reduces the risk of irritation. That said, if you have a severe nickel allergy, it's always worth consulting with a dermatologist before wearing any jewelry that isn't 100% nickel-free.

For the vast majority of people with sensitive ears or skin, 18K gold PVD on stainless steel is one of the most comfortable, irritation-free options available at this price point.

Okay, But Is It Actually Waterproof?

Here's where I'm going to be straight with you, because I think you deserve honesty over marketing speak.

The short answer is: PVD jewelry is highly water-resistant — but I'm personally not willing to call it "completely waterproof" and leave it at that.

Can you get it wet? Yes. Can you wear it in the shower occasionally without drama? Probably. Does it hold up to water exposure significantly better than traditionally plated jewelry? Absolutely. The PVD process creates a coating that resists corrosion, tarnishing, and oxidation far better than anything electroplated, and the stainless steel base doesn't rust.

But there's a difference between water-resistant and indestructible, and I think it's worth being clear about that. Prolonged, repeated exposure to harsh chemicals like chlorine from a pool, salt water, concentrated perfumes or body sprays, and harsh soaps, can degrade any coating over time, including PVD. Wearing your jewelry 24/7 through every swim, every workout, every spa day will eventually affect the finish. Not necessarily quickly, and not as dramatically as standard plating, but over time, wear is wear.

I've seen other brands make absolute guarantees about PVD jewelry being "tarnish-free for life," "safe to swim in every day," no caveats whatsoever. And look, PVD is genuinely impressive. But I'd rather give you the real picture than overpromise and leave you disappointed. Treat your PVD pieces with a little love (like you should ALL of our pieces) rinse them off after heavy exposure, pat them dry, store them properly, and they will last you a long, long time!

So Why Does Altru Jewelry Use 18K Gold PVD?

Because I got burned.

For a while, I sourced gold-filled charms through Etsy suppliers. Gold-filled sounds great on paper — and when it's the real thing, it can be. But the jewelry world is rife with suppliers who mislabel their products. What was listed as "gold-filled" wasn't always gold-filled, and I had no reliable way to verify it. That's a problem when your brand is built on doing things with integrity.

Switching to verified 18K gold PVD on stainless steel changed everything. I know exactly what I'm working with (and I can afford it). I can trust my suppliers. And I can confidently stand behind the quality of every piece I make — which, when you're a small brand asking people to spend their hard-earned money, is everything!

PVD is durable. It's accessible. It performs beautifully. And it lets me create pieces that will actually last in your jewelry collection.

That's why it's in every Altru piece that carries a gold finish. Not because it was the cheapest option, but because it was the right one.

Will I offer gold-filled ever again?

Yes! When the market stabilizes and I can trust my suppliers, I will 100% offer gold-filled options again. But for now, 18K gold PVD plated jewelry is one of the most durable, skin-friendly, and affordable options in the jewelry market. It's a legitimate step up from standard gold plating, a reliable and affordable alternative to gold-filled, and an especially smart choice for people who want jewelry that can keep up with their real life.

Will it last forever no matter what you do to it? No. But if you treat it reasonably well, it'll be with you for years.

And that's a promise I'm actually comfortable making.
