Vermeil, gold plated, gold filled, PVD. They get used almost interchangeably in jewelry listings, and they mean genuinely different things, backed by genuinely different levels of regulation. Here's what each one actually is, and why Gemiria deliberately chose none of the usual answers.
What Is Gold Vermeil?
Gold vermeil is not just an industry term, it's a legal one. Under United States FTC Jewelry Guides (16 CFR Part 23), a piece can only be called vermeil if it meets three specific requirements: the base metal must be sterling silver, the gold layer must be at least 10 karat, and that gold layer must measure at least 2.5 microns thick. Miss any one of those and it isn't legally vermeil, no matter what the listing says.
Gold Plated, Gold Filled, and Solid Gold Explained
Gold plated is the loosest of the terms. It describes a thin gold layer, often under half a micron, electroplated over almost any base metal, brass and copper are common. There's no legal minimum thickness, which is exactly why plated jewelry ranges so widely in how long it actually lasts.
Gold filled sits a step up. The gold layer is mechanically bonded under heat and pressure rather than electroplated, and by regulation it has to equal at least 5 percent of the item's total weight, meaningfully thicker than standard plating. The core underneath is still usually brass.
Solid gold is gold all the way through, no base metal, no coating. It doesn't wear thin because there's nothing under it to wear through to.
| Base Metal | Gold Layer | Method | Waterproof | |
|---|---|---|---|---|
| Gold Vermeil | Sterling silver | 10K+, 2.5 microns min (legal floor) | Electroplating | Not recommended long term |
| Gold Plated | Usually brass or copper | Often under 0.5 microns, no legal minimum | Electroplating | No |
| Gold Filled | Usually brass | Min. 5% of total weight | Mechanically bonded | Better, not full |
| Solid Gold | None, solid throughout | N/A | N/A | Yes |
| Gemiria (18K Gold PVD) | 304 surgical-grade stainless steel | 18K gold | Physical Vapor Deposition | Yes, fully |
Why Gemiria Uses Stainless Steel and PVD, Not Vermeil
Every material choice here was made on purpose, not as a compromise. This is jewelry that carries someone's actual name, sometimes a child's name, a partner's, a word that means something specific, and it's built to be worn constantly: in the shower, at the gym, while you sleep, on an ordinary Tuesday, not saved for occasions and kept safe in a box.
Gold vermeil is genuinely beautiful, but it's still a thin gold layer over a metal, sterling silver, that tarnishes on its own and eventually shows through once the gold wears thin enough. We use 304 surgical-grade stainless steel as the base and 18K Gold, 18K Rose Gold, or Rhodium Silver as the finish, applied through Physical Vapor Deposition rather than standard electroplating. PVD bonds the finish to the steel at a molecular level instead of sitting on top of it as a thin plated layer, which is why it's built to be lived in rather than protected from living. Every piece is fully waterproof and backed by a lifetime warranty, not because the material is fragile and needs the safety net, but because it isn't.
Does Stainless Steel Turn Skin Green?
No, and this is one of the more common jewelry worries with a genuinely simple answer. Skin turning green under jewelry usually comes from copper in the metal reacting with sweat and skin oils, which shows up most often in cheap gold-plated pieces where copper is part of the base or the plating itself. It's a chemical reaction, not a sign anything is wrong or dangerous, but it's also completely avoidable with the right base metal. 304 surgical-grade stainless steel doesn't cause it.
Hypoallergenic and Nickel-Free, What That Actually Means
Hypoallergenic jewelry is made from metals unlikely to trigger a skin reaction in people with sensitive skin or metal allergies, the most common trigger by far is nickel. Every Gemiria piece is hypoallergenic and nickel-free, made from 304 surgical-grade stainless steel, safe for daily wear even for people who've reacted to other jewelry in the past.
Stainless Steel vs Sterling Silver
Sterling silver is a precious metal in its own right and genuinely beautiful, but it tarnishes on its own over time, reacting with air and skin regardless of what's plated on top of it. Stainless steel doesn't tarnish. For jewelry meant to be worn every single day rather than polished and put away, that difference compounds fast. It's also why we didn't build on a sterling silver base the way vermeil does, the base metal itself was part of the decision, not just the finish on top of it.
How to Tell If Jewelry Is Real Gold
Check for a hallmark stamp first, solid gold pieces are marked with a karat number like 14K or 18K, vermeil and gold filled pieces are usually marked too. If there's no mark at all, ask directly what the base metal and gold thickness are rather than assuming. A reputable brand can answer both questions immediately. If they can't, or won't, that's the real answer.

Frequently Asked Questions
What is gold vermeil?
Gold vermeil is a legally regulated term in the US. Under FTC guidelines, it must be gold of at least 10 karat, at least 2.5 microns thick, layered over a sterling silver base. If the base isn't sterling silver, it isn't vermeil, no matter how thick the gold is.
Is Gemiria jewelry gold vermeil?
No. Gemiria's gold pieces are 18K gold PVD plated over 304 surgical-grade stainless steel, not sterling silver, so they don't meet the legal definition of vermeil. That's a deliberate choice, not an oversight, stainless steel is built for daily wear in a way sterling silver isn't.
What's the difference between gold plated and gold filled?
Gold plated jewelry has a thin layer of gold, often under half a micron, with no legal minimum thickness, over almost any base metal. Gold filled jewelry uses a mechanically bonded layer that must equal at least 5 percent of the item's total weight, which makes it noticeably more durable than standard plating.
Why does some jewelry turn skin green?
Usually from copper in the metal alloy reacting with sweat and skin oils, common in cheaper gold-plated pieces where the base or plating includes copper. It's a chemical reaction, not a sign the jewelry is dangerous, but it's also completely avoidable with the right base metal.
Is Gemiria jewelry hypoallergenic?
Yes. Every piece is made from hypoallergenic, nickel-free 304 surgical-grade stainless steel, finished in 18K Gold, 18K Rose Gold, or Rhodium Silver.
Can you shower and swim with Gemiria jewelry?
Yes, that's the point of it. Every piece is fully waterproof and backed by a lifetime warranty, made to be worn every day rather than saved for occasions.
