The short answer: the coating decides the vocabulary

The FTC Jewelry Guides, 16 CFR Part 23, govern the words on a jewelry listing, and the dividing line is durability. A coating too thin to give reasonable durability cannot be sold as "gold plated." A finish that will not survive a shower cannot be described as "waterproof," "shower-safe" or "sweat-proof," because those are durability claims. Flash plating under 0.5 micron marketed that way is the example §23.1 points to.

Where the Guides get their force

The Guides are not a standalone statute. They are FTC guidance the agency uses when applying Section 5 of the FTC Act, which is the provision that makes a misleading claim actionable. That distinction is practical rather than academic: it explains why the wording matters even though no single rule bans a phrase outright.

Platforms fold the same standard into their own rules, and TikTok Shop's current policy bars listings that violate the Guides. Platform policy changes often, the Guides change rarely, and both are worth checking before a launch rather than after a complaint. The practical consequence is blunt: the same piece can be listed legally with one set of words and unlawfully with another, and nothing about the product changes except the copy.

The tiers, and the words each one earns

Flash plating, under 0.5 micron: color only. A flash coat is a color, not a protective layer. Gold-tone, gold-colored and gold finish are defensible at that thickness. "Gold plated" is not available, because the reasonable-durability standard is not met, and the waterproof family runs straight into §23.1.

0.5 to 1 micron: light-wear "gold plated." The phrase holds at this range when the thickness is documented and the wear expectations are honest. Pair it with care wording such as removing the piece before swimming or applying perfume, and leave waterproof language out entirely.

1 to 2 microns: daily-wear "gold plated." This is the standard daily-wear tier for plated fashion jewelry, and thickness data behind it supports the durability claim. Waterproof wording still needs testing on the exact finish you ship, which is why most plated brands stay with care-based phrasing.

Vermeil: 2.5 microns of gold over 925 sterling silver. Vermeil is a defined construction rather than an upgrade. Plated brass sold as vermeil is a different product, not a stretch of wording. Our gold vermeil manufacturing page covers how the construction is specified.

PVD: name the process. PVD is a different coating method, so describe it as one, with wording like "gold PVD finish." Do not borrow the vocabulary of the plating tiers for a coating that was applied by a different process.

Three words, each with one job

  • Gold-tone describes a color and makes no plating claim. Safe on any gold-colored finish.
  • Gold plated claims a gold coating of reasonable durability, and the thickness documentation has to back it.
  • Vermeil names a construction: 2.5 microns of gold over 925 sterling silver.

Each of the three is a description rather than a compliment. It either matches the construction or it does not.

What stands behind the words

Claims are defended with paper. Ask for plating thickness data measured by XRF, per batch, and keep it with the listing records. If a claim is ever questioned by the FTC, a platform or a competitor complaint, that measurement report is the document that answers it. The plating thickness guide lists the bands, and the XRF verification guide explains what a measurement report should contain.

Our own plating runs in four layers: a nickel barrier, a copper layer, the gold layer, and a protective top coat, with the thickness range stated per order. The four-layer plating page shows how the stack is built and why the barrier layer matters for wear.

Here is an illustrative scenario, not a claim about a named customer or a published Qiuqiu Atelier order. A brand listed a $22 plated-brass necklace as "18k gold plated, waterproof, shower-safe." The order specification, however, was flash plating chosen to hit the price point. Two claims failed at once: "gold plated" outran the durability of the coating, and "waterproof" on flash plating is the exact wording §23.1 flags. The relaunch kept the same product and changed the words: gold-tone finish, care instructions instead of water promises, and the plating report filed with the listing records.

Before writing listing copy, ask any supplier two questions: what thickness range does this finish carry, and can I have the measurement data per batch. A factory that cannot answer both is not one to build durability claims on. The materials and plating overview shows how the specification comes back in writing. To start that conversation, send the finish and the claim you intend to publish through the Qiuqiu Atelier quote form.

FAQ

At what thickness can I start saying "gold plated"?

Once the coating meets the reasonable-durability standard the Guides describe, which in practice means the thickness is documented and the wear expectation is realistic. Flash plating under 0.5 micron generally does not qualify, so gold-tone or gold-colored is the safer wording at that end of the range.

Is "waterproof" ever acceptable on plated jewelry?

Read it as a durability claim, and durability claims need support. On flash plating it is the example §23.1 identifies as misleading; on any plated piece it should rest on testing of the exact finish you ship. "Remove before swimming" is far easier to defend than a blanket promise.

What separates gold plated from vermeil?

A defined construction. Vermeil means 2.5 microns of gold over 925 sterling silver, and nothing else qualifies. Gold plated covers a range of coatings that pass the durability standard. Selling plated brass as vermeil is a materials mismatch rather than a wording choice.

Where does PVD fit in these tiers?

Outside them. PVD is a different coating process, so the honest approach is to name it directly, as in "gold PVD finish" or "gold-tone PVD," rather than borrowing the vocabulary reserved for electroplating and vermeil.

Which claims are safest to publish?

Specific ones. A stated base metal, a stated plating thickness and care instructions survive scrutiny better than any superlative, because each can be checked against a document. Keep the plating report with the listing records, and the answer to a challenge is already written.
