Understanding FTC Silver Jewelry Standards: What Sellers Must Disclose

I am going to argue something that may be unpopular in my own industry: the FTC’s silver jewelry standards are mostly good rules, badly enforced. The rules themselves, found at 16 CFR Part 23, are clear enough that any honest seller can follow them. The problem is that the rules are complaint-driven, the marketplace is global, and the platforms that move most of the volume have no legal obligation to pre-verify what their sellers claim. The result is a regulatory framework that protects buyers in theory and leaves them exposed in practice. If you sell silver, you should know these rules. If you buy silver, you should know them even better, because you are the one the rules expect to file the complaint.

What the FTC Actually Regulates

The relevant document is the FTC’s “Guides for the Jewelry, Precious Metals, and Pewter Industries,” codified at 16 CFR Part 23. The silver-specific provisions are in section 23.5. The FTC last revised these guides in 2018, with the revision published in the Federal Register at 83 FR 40667. The 2018 update modernized some language, but the core rules on silver have been stable for decades.

It is worth being precise about what these guides are. They are not statutes passed by Congress. They are administrative guides issued by the FTC under its authority to police unfair or deceptive acts under 15 U.S.C. 45. The guides tell sellers what the FTC considers deceptive. If a seller violates the guides, the FTC can bring an enforcement action for unfair or deceptive trade practices. The guides also overlap with the older National Stamping Act (15 U.S.C. 294 et seq.), which sets specific tolerances and prohibitions on marking silver-plated items as sterling.

In plain terms: the FTC sets the labeling rules, and if you break them, the FTC can come after you. But the FTC does not pre-approve labels, does not test metal before sale, and does not run a compulsory assay system. The rules are enforced after the fact, usually after complaints.

The Core Silver Rules in Plain English

Section 23.5 is short enough to summarize directly. Here is what it says, stripped of the legal phrasing.

You Cannot Use “Silver” Unqualified Without a Fineness Number

Under 23.5(b)(1), if you use the word “silver” to describe a product, you must precede it with an equally conspicuous, accurate fineness designation in parts per thousand. So “925 silver” is compliant. Bare “silver” alone is not, because it does not tell the buyer the purity. This rule exists to stop sellers from implying high purity through vague language. The 2018 revision clarified that you can use “silver” for alloys below 925, as long as you state the actual fineness, like “750 silver.” Before that, there was ambiguity about whether anything below sterling could be called silver at all.

“Sterling” Means 925, Period

Under 23.5(b)(2), the terms “solid silver,” “Sterling Silver,” “Sterling,” and the abbreviation “Ster.” can only be used if the product is at least 925 parts per thousand pure silver. This is the hard rule. If a piece is stamped “sterling” and is not 92.5% silver, the seller has broken the law. There is no wiggle room here. This is the rule most counterfeiters violate, and it is the rule buyers should invoke when they discover a fake.

“Coin Silver” Means 900

Under 23.5(b)(3), “coin” or “coin silver” requires at least 900 parts per thousand pure silver. This is a mostly historical category, common in 19th-century American silver, but the rule still matters for antique sales. A piece sold as “coin silver” must be 90% silver, not less.

Plated Must Be Disclosed

Under 23.5(b)(4), if a product is not silver throughout but has only a surface coating of silver, the word “silver” must be adequately qualified to indicate the product is only coated. So “silver-plated,” “silver-coated,” or similar qualified terms are required. Bare “silver” on a plated piece is deceptive. This is the rule that catches sellers who use “silver” to describe plated items without the qualifier.

Plating Must Have “Reasonable Durability”

Under 23.5(b)(5), you cannot call something “silver plated” unless all significant surfaces actually have a silver plating of reasonable durability. A piece with a microscopically thin flash of silver that rubs off in a week does not meet this standard, even if it technically has some silver on it. This rule is harder to enforce because “reasonable durability” is subjective, but it exists to stop sellers from labeling borderline plating as plated.

The National Stamping Act Adds Teeth

Layered on top of the FTC guides is the National Stamping Act, codified at 15 U.S.C. 294 et seq. This is an actual statute, not just a guide. It prohibits stamping silver-plated articles with “sterling” or “coin,” either alone or with other words. It also sets the permissible tolerances: sterling silver parts without solder can deviate by no more than 4 parts per thousand, and parts with solder can deviate by 10 parts per thousand. So a “sterling” piece that tests at 920 is technically out of tolerance if it has no solder, and at 915 if it does. These tolerances matter for honest makers, because minor alloy variations in production can put a piece just under spec if the mix is not controlled.

What Sellers Must Disclose

Putting the rules together, here is what an honest seller of silver jewelry must do.

• If the piece is solid sterling, stamp or describe it as “sterling,” “925,” or “solid silver,” and ensure the metal actually meets 925.
• If the piece is a lower-purity silver alloy, state the fineness clearly, like “900 silver” or “800 silver.”
• If the piece is silver-filled, disclose it as filled, with the proportion, like “1/10 925 silver-filled.”
• If the piece is silver-plated, say “silver-plated” or “silver-coated,” and ensure the plating has reasonable durability on all significant surfaces.
• Never stamp a plated piece as “sterling” or “coin,” under any circumstance.
• Do not use bare, unqualified “silver” without a fineness number.
• Stay within the National Stamping Act tolerances on actual silver content.

That is the whole rulebook in practical terms. It is not complicated. Any seller who claims the rules are too complex to follow is either not trying or is benefiting from the confusion.

Where the Rules Fall Short

Here is my opinion, and it is not a popular one in some circles. The rules are sound, but the enforcement architecture has two structural gaps that leave buyers exposed.

Gap One: No Pre-Sale Verification

The United States has no compulsory assay system. A seller stamps their own pieces and relies on their own testing, or on no testing at all. The FTC only acts after a complaint, and complaints typically come only after a buyer has already been harmed. This means the system catches bad actors reactively, one buyer at a time, while the bad actor sells to thousands more in the interim.

Compare this to the British system, where an independent assay office tests every piece before it can be legally sold as sterling. The British system is more expensive and slower, but it raises the cost and risk of counterfeiting dramatically. I am not arguing the US should adopt a full assay system, because that would be a heavy regulatory burden on small makers. But the absence of any pre-sale verification is a real gap, and buyers should understand that the absence of an assay mark on American silver is not a sign of dishonesty, it is a sign that the burden of verification falls on them.

Gap Two: Cross-Border Enforcement

Most of the counterfeit silver entering the US market comes from overseas sellers operating through online marketplaces. The FTC has jurisdiction over deceptive trade practices affecting US consumers, but pursuing an overseas seller who has already closed their account and reopened under a new name is practically impossible. The platforms have policies against misrepresentation, but they are not legally liable for the content their sellers post, thanks to safe-harbor principles that predate the modern e-commerce era. So the worst offenders operate with near-impunity, and the rules primarily constrain the honest domestic sellers who were going to follow them anyway.

This is the frustrating paradox of the FTC silver rules. They work well to keep honest sellers honest. They do little to stop the flood of counterfeit listings that do the actual damage, because those listings sit outside the FTC’s practical reach.

The 2018 Revision: What Changed and What Did Not

The 2018 revision to the guides made a few meaningful changes worth knowing about. The most significant for silver was the clarification that you can use “silver” to describe an alloy below 925, as long as you state the actual fineness. Before 2018, there was ambiguity about whether “silver” without qualification implied sterling. The revision resolved that: “silver” is fine, but it must be paired with an accurate parts-per-thousand number. This helps sellers of legitimate lower-purity alloys, like German 800 silver, describe their products accurately without implying sterling.

The revision also addressed some non-silver issues, like removing the previous requirement that a product contain no non-precious metal to be called “gold” or “silver” in certain contexts, and clarifying treatment of lead content. For silver specifically, the core 925 rule for “sterling” was unchanged, because it has been settled law for a century.

What the revision did not do is add any new enforcement mechanism. The guides remain complaint-driven. If anything, the cross-border problem has gotten worse since 2018, as online marketplace volume has grown and overseas seller networks have become more sophisticated. The rules are clearer, but the practical protection for buyers has not improved proportionally.

What This Means for Buyers

If you are buying silver, the FTC rules give you a tool, not a shield. The tool is this: if a seller describes a piece as “sterling” and it turns out not to be 925 silver, the seller has violated federal law, and you have grounds for a refund, a chargeback, and a complaint. The rules do not prevent the violation, but they give you recourse after the fact.

Concretely, if you test a “sterling” piece and it fails, you can cite 16 CFR 23.5(b)(2) in your return request or chargeback. Mentioning the specific regulation gets attention, both from the seller and from the platform’s dispute resolution team. It signals that you know your rights and that you are not going to accept a vague “sorry, no returns” response. The FTC rules are your leverage, even if the FTC itself is unlikely to pursue your individual complaint.

You can also file a complaint with the FTC directly at reportfraud.ftc.gov. The FTC does not resolve individual disputes, but complaints aggregate. If enough buyers complain about a seller or a listing pattern, the FTC may take action, as it has in past sweeps against jewelry sellers for misrepresentation. Your individual complaint contributes to the pattern that eventually triggers enforcement.

What This Means for Sellers

If you sell silver, the rules are not optional, and they are not that hard. At lhcjewelry.com/ we follow them, and we publish our metal sourcing because transparency is the cheapest marketing there is. The rules ask for three things: accurate fineness claims, clear disclosure of plating or filling, and no use of "sterling" on non-sterling metal. Any seller who cannot meet those three requirements should not be selling silver.

The sellers who get into trouble are usually the ones who see the rules as obstacles to work around rather than standards to meet. The vague “real silver” phrasing, the bare “925” on filled pieces, the “silver tone” buried in fine print under a “sterling” title, these are all attempts to extract sterling prices without meeting sterling standards. The FTC rules exist to make those strategies legally risky. They are not foolproof, but they give honest sellers a competitive floor and give buyers a basis for pushing back.

The Case for Stronger Enforcement

My own view is that the FTC rules need more enforcement, not more language. The 2018 revision was useful, but the underlying problem is that complaint-driven enforcement cannot keep up with marketplace-scale counterfeiting. A few targeted sweeps against high-volume counterfeit sellers, with publicized penalties, would do more to clean up the market than another round of guide revisions.

I would also like to see the major marketplaces take more responsibility for pre-screening silver claims. Amazon and Etsy could require silver listings to include a hallmark photo and a fineness disclosure, and could delist sellers with repeated misrepresentation complaints. They have the data to do this. What they lack, so far, is the incentive, because counterfeit listings generate fees along with genuine ones. Regulatory pressure on the platforms, not just on individual sellers, is probably the most effective lever available.

The Rules Are on Your Side, If You Use Them

The FTC silver jewelry standards are not perfect, but they are better than nothing, and they are better than most buyers realize. The 925 rule for sterling is clear and absolute. The plating disclosure rule is clear. The National Stamping Act prohibition on stamping plated items as sterling is clear. The tools exist. What is missing is broad awareness that the tools exist, and the willingness of buyers to use them.

If you buy silver, learn the rules in 16 CFR 23.5. They are short, they are readable, and they tell you exactly what a seller can and cannot claim. If a seller breaks the rules, you have recourse. If enough buyers exercise that recourse, the market gets cleaner, one complaint at a time. The rules will not protect you automatically. But they will protect you if you know them and act on them.

State-Level Rules and Lead Content

Beyond the federal rules, a few state laws affect silver jewelry sold in the US. California’s Metal-Containing Jewelry Law, passed in 2006 and effective since 2007, restricts lead content in jewelry, including adult jewelry, to specific limits. For silver jewelry, the lead limit is 1.5% by weight for adult jewelry and 0.06% for children’s jewelry. This matters because some imported silver, especially older stock and some Mexican production, can contain lead as a trace element. Reputable modern production tests for lead and stays well under the limit, but the California rule exists because the problem was real enough to legislate.

If you sell silver jewelry nationally, you need to comply with California’s lead limits even if you are based elsewhere, because the law applies to jewelry sold to California residents. The practical effect is that most domestic makers now source low-lead sterling alloy, and the lead issue is largely handled at the supply level. But buyers should know the rule exists, especially for imported or vintage pieces where lead content may not have been controlled.

How the Tolerances Work in Practice

The National Stamping Act tolerances deserve a practical explanation, because they confuse sellers. The act allows sterling to test slightly below 925 without being considered misbranded, to account for the realities of alloying and soldering. The tolerance is 4 parts per thousand for parts without solder, meaning a piece can test as low as 921 and still be legally sterling. For parts with solder, which dilutes the silver, the tolerance is 10 parts per thousand, meaning a soldered joint can test as low as 915.

This matters for makers because soldering a ring shank, attaching a clasp, or joining a chain link all introduce non-silver metal at the joint. If you test only the joint, you get a lower reading than if you test the main body. Honest makers know this and test the body, not the joint. But it also means a piece that tests at 922 at the body is legally compliant, even though it is technically below 925. The tolerance is not a loophole; it is a recognition that real-world alloying is not perfectly precise.

For buyers, the takeaway is that an XRF reading of 925 exactly is not required. A reading between 921 and 929 is normal for genuine sterling, and a reading at a soldered joint that is lower still is also normal. If a piece tests at 900 or 850, it is not sterling regardless of tolerance. If it tests at 923 at the body, it is sterling.

What the FTC Has Actually Done

The FTC does enforce its jewelry rules, though infrequently relative to the scale of the market. Past enforcement actions have targeted sellers who misrepresented gold content, plated items as solid, and synthetic stones as natural. The FTC has brought cases against online sellers for misrepresenting jewelry materials, and these cases typically end in consent decrees with monetary penalties and injunctions against future misrepresentation. The Jewelers Vigilance Committee, an industry group, works with the FTC and also brings its own actions against misrepresenting sellers.

The pattern is that enforcement happens in sweeps, not continuously. The FTC will identify a category of abuse, gather complaints, and bring several actions at once to signal to the industry that the behavior is being watched. Between sweeps, enforcement is complaint-driven and slow. This is why individual buyer complaints matter: they build the record that triggers the next sweep. A single complaint may not produce action, but hundreds of complaints about the same type of misrepresentation can.
