Three gold chains. Three very different stories underneath.

A few weekends ago I tried a small experiment at Ripe Market.

I laid three gold chains next to each other on my linen cloth. Same length. Almost the same thickness. Almost the same warm colour. One was vermeil. One was stainless steel. One was gold-plated brass. Then I asked everyone who stopped by to guess which one cost the most.

Most people picked the wrong one. A few picked the right one for the wrong reason. One girl held all three up to the light for a full minute, then put them down and said, "Honestly? They're the same necklace."

They are not the same necklace. But I understand why it looks that way.

In my beginner's guide I explained what each of these materials is. This post is about what that guide left out. what each one costs the planet, what each one costs you and why those two costs don't line up the way you would expect.

The Gold Is the Smallest Part (And the Heaviest)

All three chains looked gold. Only two of them actually had gold on them. On both, the layer was thinner than you would believe.

Ordinary gold plating can be as thin as 0.175 microns. For scale a single strand of human hair is somewhere around 70 microns wide.

Vermeil is different. It needs at least 2.5 microns of gold over sterling silver and that gold has to be at least 10 karat. That is the US Federal Trade Commission's definition and it is the one most brands point to. If the layer is thinner the piece is supposed to be called gold-plated sterling silver not vermeil.

So vermeil carries more than ten times the gold of a thinly plated piece. By weight that is still tiny. On a pair of small studs, it's a few hundredths of a gram.

Here is what surprised me, though. Gram for gram, gold is one of the most destructive materials we pull out of the ground. The mining watchdog Earthworks estimates that making a single gold ring leaves behind around 20 tonnes of mine waste.

Put those two facts together and you get an awkward conclusion. The "premium" option in this comparison has the most gold on it. So unless that gold is recycled, its finish carries the biggest mining footprint of the three.

More gold makes a piece last longer. It does not automatically make it kinder.

What's Underneath Matters More Than What's on Top

The gold layer gets all the attention. But most of the metal in each piece is the base, and the three bases have very different backstories.

Vermeil sits on sterling silver. Most silver isn't mined for its own sake. Roughly 70 to 80 percent of it comes out of the ground as a by product of mining copper, lead and zinc. That doesn't make silver impact-free. But its footprint is tangled up with mines that were digging for other metals anyway. Recycled sterling silver is also widely available. If a brand uses it, they will usually say so.

Stainless steel is mostly iron, chromium and nickel. It's one of the most recycled materials in the world. Around 95 percent of stainless steel is collected at the end of its life and new stainless contains about half recycled scrap on average (much more in Europe and the US). Those numbers cover all stainless steel from kitchen sinks to buildings not just jewelry. But they show how much of this metal keeps coming back.

The bit I did not expect, gold-tone stainless jewelry often contains no gold at all. The colour usually comes from PVD coating which stands for physical vapour deposition. It is a vacuum process and the coating is often a compound like titanium nitride that just looks gold. It is tougher than traditional plating and it skips the cyanide based chemical baths that most gold plating relies on. Whether "no real gold" sounds like a letdown or a relief depends on what you care about.

Brass is copper and zinc. Copper mining has a heavy footprint of its own. But brass is one of the most recycled alloys there is and a lot of new brass starts life as scrap. The bigger environmental question with brass jewelry is usually the plating, not the metal. To look gold, brass is electroplated, and most of its chemical footprint is in the plating shop's wastewater.

There's one more thing worth knowing. Lead is sometimes added to cheaper brass to make it easier to machine. The EU limits lead in jewelry to 0.05 percent by weight and good suppliers will tell you their brass is lead free. If a supplier can't answer that question, that is your answer.

Where Your Money Actually Goes

This is the part that changed how I read price tags.

With vermeil, you are mostly paying for silver. Silver prices have climbed a lot over the past couple of years. Add labour and the brand name, and the gold ends up being a fairly small share of the price. So when a vermeil piece costs three or four times as much as the brass version, you aren't getting three or four times the gold. You're getting a solid precious-metal base with a thicker gold layer on top.

With stainless steel, the metal itself is cheap. The work isn't. Steel is hard to cut, shape and solder, which is why stainless designs tend to be cleaner and simpler. Most of what you pay covers machining and coating, not the raw material.

With brass, the base is the cheapest of the three. Brass is soft and easy to cast, so the most detailed, sculptural designs at accessible prices are almost always brass. Most of the cost goes into plating and finishing. And plating thickness is usually the first thing that gets cut when a brand chases a lower price.

That is why two brass pieces that look identical in a photo can be completely different pieces of jewelry. One might have a properly thick layer. The other might have barely enough gold to change the colour. The listing will often look exactly the same.

The Question Nobody Asks: What Happens at the End?

Every comparison I found online stopped at "how long does it last?" Almost none asked what happens once it doesn't.

Vermeil can be brought back. When the gold wears thin, a jeweller can replate it. And because the base is real silver, it keeps genuine value. Jewellers will buy it, melt it and use it again. It has a real second life.

Stainless steel almost never wears out, but it's hard to fix. Most small workshops can't easily resize or solder it. Once a PVD coating wears through at a high-friction spot, like the inside of a ring, recoating it isn't something your local jeweller does. Stainless lasts the longest of the three, but it's also the hardest to repair.

Brass is recyclable on paper and thrown away in real life. It can be replated cheaply, which is a real advantage. But a single brass earring is worth almost nothing as scrap, so nobody collects it. The metal can be recycled. The piece usually isn't.

That last point taught me something I now apply everywhere. "Recyclable" means very little unless the object is valuable enough for someone to actually bother.

The Honest Scorecard

If I had to sum up the three chains on my linen cloth, this is how it would go.

Vermeil has the most precious metal, the highest price and the most gold-mining footprint unless the gold is recycled. In return, it holds real value and can be repaired and recycled.

Stainless steel needs the least care, has a strong recycled story and uses the cleanest coating process. It also has the simplest designs and is the hardest to repair.

Brass has the lowest price and the most design freedom. Its environmental impact depends almost entirely on the plating shop, and the piece will rarely be recycled at the end, even though the metal could be.

There is no winner here. Each one wins a different category. Anyone who tells you one material is simply "the sustainable one" is skipping most of the story.

How I Decide Now

I stopped asking which material is best and started asking which material is right for this piece, for this person.

For everyday pieces that will face sweat, water and a Dubai summer, I lean towards stainless steel. They will be worn hard, and stainless handles that better than anything else here.

For textured, sculptural designs that need fine detail, brass makes sense. But only from suppliers who will tell me the plating thickness and confirm the brass is lead-free.

For pieces meant to be kept for years, maybe passed on one day, vermeil earns its price. But only if it really meets the 2.5 micron standard, and ideally with recycled silver underneath. I would rather honestly call something gold-plated sterling silver than stretch the word vermeil to make it sound better.

The Questions Worth Asking

Before buying any of these three, a few questions will tell you more than the product photos ever will.

How thick is the gold, in microns? If nobody can tell you, assume it's thin.

Is the silver or gold recycled? For vermeil especially, this changes the impact more than anything else.

For gold-tone steel, is it PVD or plated? PVD lasts much longer. Plated steel gives up most of the advantage of choosing steel in the first place.

For brass, is it lead-free? A good supplier answers this in one sentence.

And if it wears out, can it be fixed, and by whom? A piece that can be repaired keeps going. A piece that can't usually ends up in the bin.

Back to the Linen Cloth

That girl at the market wasn't wrong, exactly. From a metre away, the three chains really were the same necklace.

Up close, they couldn't be more different. Different thicknesses of gold. Different mines. Different chemical baths. Different futures five years from now. The price tag only tells you one of those stories.

Now you know how to ask for the rest.
