Gold jewelry labels sound like a ranking. Vermeil sounds fancy. Gold-filled sounds generous. Gold-plated sounds like the one your friend warned you about.
That ranking is mostly vibes. Each word describes a different way of building a piece, and none of them tells you the two things that decide how it wears: how much gold is on the surface, and what happens where it rubs.
We make gold-plated jewelry, so you can decide how much to trust us here. We'd rather you trust the definitions, so here they are.
What the words mean, legally
In the US, these terms come from the FTC's Jewelry Guides. The thresholds below are the FTC's guidance for using each word honestly.
| Label | What's underneath | The gold |
|---|---|---|
| Gold-plated | Any metal | At least 10K, electroplated, with a minimum of 0.175 microns of pure-gold equivalent |
| Vermeil | Sterling silver | At least 10K, at least 2.5 microns of pure-gold equivalent |
| Gold-filled | Usually brass | At least 10K, bonded with heat and pressure, at least 1/20 of the piece's metal weight |
| Gold flashed or washed | Any metal | Thinner than plating. The FTC stopped endorsing these terms in 2018 because shoppers didn't realize what they meant |
| Demi-fine | Anything | No legal definition at all. It's a price and quality tier, not a material |
A few things jump out. "Gold-plated" covers an enormous range, from a coating barely past the minimum to one more than ten times thicker. Vermeil is really a statement about the base: sterling silver. And gold-filled is measured by weight, not thickness, which is why it's usually reserved for chains and simple wire hoops.
The detail almost nobody mentions: karat changes the math
Here's the part most brands skip. The FTC counts plating thickness in pure-gold terms. One micron of 12K gold, which is half gold, counts as half a micron.
So when a brand says "2.5 microns," ask what karat. A thickness without a karat is only half a spec, which is why we publish both: 2.5 microns of real 18K gold on every Heavy Gold+ ring.
A label tells you how a piece was made. The numbers tell you how it will wear.
Why our rings aren't vermeil
It's the question we get most, so here's the straight version.
Vermeil's big selling point is what's underneath. If the gold wears through, you see silver instead of a base metal. On paper, that's a real advantage. On your hand, a gold ring with silver showing through still isn't the gold ring you bought. Either way, the moment the gold goes, the ring has changed.
So the part worth paying for is the gold itself, and how long it stays put. That's where we spend. Our gold isn't plated straight onto a base metal: it goes onto a real silver layer, the same surface it bonds to in vermeil, and that silver keeps the core from creeping into the gold over time. Then comes 2.5 microns of real 18K gold, and a clear protective seal over the top.
A solid sterling silver base costs more, and every dollar of it goes into the part of the ring you never see. It doesn't add a micron of gold to the part you do. Putting that money into the surface instead is how a ring with real 18K gold, hand-set stones and a two-year warranty still comes in under $100.
Why we don't make gold-filled
Gold-filled is tough stuff. It's made by bonding a thick layer of gold alloy to a base metal with heat and pressure, then rolling it into sheet or drawing it into wire. That's why it's everywhere in chains, wire hoops and plain bands.
It's also why it can't do what we do. Gold-filled is worked from sheet and wire, not cast, so there's no pouring it into a sculpted shape. Cut it, file it or drill it, and the core shows at every edge. Even soldering it takes care, because too much heat starts mixing the layers.
Our rings start as sculpted forms: bands that curve, dip and split, bezels and prongs that hold stones set by hand, charms and drops that hang and swing. A design like Spell, with its curved band and five swinging bezels, is exactly what gold-filled was never built for. So is most of what we make.
If a plain gold band is all you're after, gold-filled is a perfectly good choice. We didn't start Oomiay to make plain gold bands.
Want solid metal all the way through?
Many of our designs also come in .925 sterling silver: solid silver from the inside out, finished in rhodium like fine white gold. Same designs, solid metal.
What to ask instead
Skip the label and ask four questions. Any brand that knows its product can answer them in one line each.
- What karat is the gold?
- How thick is it, in microns?
- What's underneath it?
- How long is the warranty?
If the answers are vague, so is the product. Ours are on our materials page: 18K, 2.5 microns, brass with a silver barrier, and a two-year warranty.
Labels are a starting point. Numbers are the answer.

Sakura RingQuestions about gold jewelry labels
Is vermeil better than gold-plated?
Not automatically. Vermeil guarantees a sterling silver base and a minimum gold thickness. A well-made gold-plated piece can carry a comparable amount of gold, so check the karat and thickness rather than the label.
Is gold-filled real gold?
Yes. Gold-filled jewelry has a layer of real gold alloy, at least 10K, bonded to a base metal with heat and pressure. The gold must make up at least 1/20 of the piece's metal weight.
What does demi-fine jewelry mean?
Demi-fine has no legal definition. It describes jewelry that sits between fashion jewelry and fine jewelry in price and quality, usually made with real gold or silver over a base, with better construction than fast fashion.
Why isn't Oomiay jewelry called vermeil?
Vermeil requires a solid sterling silver base. Oomiay's Heavy Gold+ rings plate 2.5 microns of 18K gold onto a real silver layer over the core, so the gold still bonds to silver. Putting the cost into the gold and a protective seal, rather than a solid silver base, keeps our gold rings under $100.
Why doesn't Oomiay make gold-filled jewelry?
Gold-filled is made from sheet and wire rather than cast, and cutting, filing or drilling it exposes the core. That works for chains and plain bands, but not for sculpted bands, hand-set stones and moving charms, which is most of what Oomiay makes.
Does Oomiay sell solid sterling silver?
Yes. Many Oomiay designs come in .925 sterling silver, finished in rhodium like fine white gold.
