18K gold PVD, gold plated or solid gold: which should you buy?

Gold jewellery is sold in Australia under at least five different descriptions, most of which are designed to sound like solid gold without being it. Gold plated, gold filled, gold vermeil, PVD gold, solid gold. They are wildly different products at wildly different prices, they wear in completely different ways, and only some of them are safe to put in a piercing.

This guide explains what each one actually is, how long it lasts, and which to buy. We make gold PVD over titanium, so you should read this knowing where we sit, but we have tried to be straight about what our own finish will and will not do.

The short answer

For a piercing, buy either solid gold at 14K or 18K, or gold PVD over implant grade titanium. Avoid gold plated and gold vermeil in anything that goes through your skin, and treat gold filled as acceptable for earrings that sit on the outside but not for a healing piercing. The thing that matters is not the gold. It is what is underneath it.

The five kinds of gold, plainly

Solid gold

Gold all the way through, alloyed with other metals for hardness. 14K is 58 percent gold, 18K is 75 percent. It never wears off, because there is no coating to wear. It is also the most expensive by a long way, and it is heavy, which some people love and some notice by the end of the day.

The catch is the alloy. Pure gold is far too soft, so it is always mixed with something, and in cheaper gold that something can include nickel. White gold in particular is often alloyed with nickel to achieve the colour. If you are buying solid gold and you have sensitive ears, ask what the alloy contains. A good jeweller will tell you.

Gold filled

A thick layer of gold mechanically bonded to a base metal core, legally required to be at least five percent gold by weight. It is far more substantial than plating and can last years on an item worn outside the skin. It is a genuinely decent product for earrings, chains and bracelets.

It is still a layer over a base metal, though, and the base is usually brass. For a piercing that sits in an open channel, we would not use it.

Gold vermeil

Gold plating over sterling silver, with a minimum thickness required to use the name. Better than ordinary plating because the base is silver rather than brass, so there is no nickel underneath. But the plating is still thin, silver tarnishes once exposed, and vermeil does not cope well with moisture. Fine for occasional wear, poor for a piercing you sleep in.

Gold plated

A microscopically thin layer of gold deposited on a base metal, often measured in fractions of a micron. This is what most cheap gold coloured jewellery is. It wears through quickly, sometimes in weeks, and what is underneath is usually brass or a nickel bearing alloy. In a piercing this is the worst option available, because the moment the plating wears you have nickel sitting in an open wound.

Gold PVD

Physical vapour deposition. The piece goes into a vacuum chamber and a gold coloured material is vaporised and bonded to the surface at a molecular level. The result is far harder and far more scratch resistant than electroplating, and it does not flake. It is the same process used on high end watch cases and surgical tools.

PVD is still a surface finish rather than solid gold, so it will eventually wear at high friction points. The reason it works for piercing jewellery is what sits underneath. When PVD is applied over implant grade titanium, a worn patch exposes more titanium, which is nickel free and completely safe. When it is applied over steel, a worn patch exposes nickel.

What we make, and how long it lasts

Our gold is 18K gold PVD over ASTM F-136 implant grade titanium. We describe it that way deliberately, rather than just calling it gold, because the difference matters and we would rather you knew what you were buying.

We tell people it stays colourfast for roughly two to three years of normal daily wear. That is an honest figure rather than a flattering one. Anyone selling a plated finish at this price point and promising it lasts a lifetime is either using solid gold or guessing. PVD is hard, but it is not permanent, and how long yours lasts depends on where the piece sits and how much friction it gets.

What we can say without qualification is that when it does eventually wear, nothing harmful is exposed. That is the whole reason we chose titanium as the base rather than steel.

How to make gold last longer

  • Take it off for the pool and the ocean. Chlorine and salt are hard on any finish.
  • Put jewellery on last. Perfume, hairspray, sunscreen and fake tan all attack plating and PVD.
  • Do not scrub it. Warm water, a drop of mild soap and a soft cloth. No polishing cloths, which are abrasive and designed to remove a surface layer.
  • Avoid ultrasonic cleaners. They are fine for solid metal and unkind to finishes.
  • Rotate your pieces. The piece you wear every single day wears fastest. A small collection lasts longer than one favourite.
  • Wear the unplated titanium while healing. Bare metal is the safest thing for an open piercing, and it saves the gold from the roughest months.

Is gold worth it for a piercing?

If you mean solid gold, it is worth it when you want something permanent and you have the budget, and it is the only option that genuinely never changes. Expect to pay several times what titanium costs for the same shape.

If you mean PVD gold over titanium, yes, with clear eyes. You are buying the colour and the look, on a piece whose safety does not depend on the finish surviving. You will probably want to replace it in a few years, which is worth factoring in. Many people buy titanium in silver tone for the pieces they never take out, and gold for the visible statement pieces they change more often. That is a sensible way to split a budget.

What is never worth it for a piercing is gold plating over an unspecified base metal, no matter how good the photo looks or how low the price is.

Frequently asked questions

Will PVD gold turn my ear green?

No. Green staining comes from copper in cheap alloys reacting with skin. There is no copper in implant grade titanium and none in the PVD layer.

Can I wear gold in a healing piercing?

We would not. Bare implant grade titanium is the safest thing for an open wound, and healing is the period of heaviest wear on any finish. Wear titanium for the first few months and switch to gold once it has settled.

Is 18K PVD the same as 18K gold?

No, and it is worth being clear about. 18K describes the colour and tone of the finish, not the composition of the whole piece. The piece is titanium with a gold coloured surface. Anyone implying otherwise is being slippery.

Does PVD wear evenly?

Mostly, but high friction points go first. On a labret that tends to be the edge of the disc where it sits against the skin, which is the part nobody sees. Visible tops usually keep their colour longest.

Can I mix gold and silver tone pieces?

Absolutely, and it looks intentional when it is done with a bit of structure. Our guide to mixing gold and silver covers how to keep a two-tone ear looking deliberate.

How to read a gold listing in Australia

Most of the confusion in this category is deliberate, so it helps to know the tells. A listing that says gold tone, gold colour or gold finish is telling you there is no meaningful gold content at all. A listing that says 18K without the words solid or PVD is usually describing the colour of a coating rather than the composition of the piece. Anything that says gold over stainless steel is telling you the base is nickel bearing, whether or not it puts it that way.

What an honest listing looks like is specific and slightly less exciting. It names the base metal and its standard, it names the finish and the process, and it does not promise permanence. Ours reads 18K gold PVD on ASTM F-136 implant grade titanium, which is a mouthful and is exactly the point.

One more test worth applying: if the seller quotes a plating thickness in microns, they probably know what they are selling. If they cannot answer what is underneath the gold, that is your answer.

A word on white gold

White gold deserves its own warning if you have sensitive ears. Gold is naturally yellow, so white gold is made by alloying it with a white metal, and historically that metal has very often been nickel. It is then usually rhodium plated on top to get the bright white finish, and when that rhodium wears, which it does, you meet the alloy underneath.

This catches people out because white gold feels like a premium purchase, and premium is not the same as nickel free. If you want a silver tone in a piercing and you react to things, implant grade titanium is the straightforward answer. Palladium white gold exists and is nickel free, but you have to ask, and it costs considerably more.
