Module 6: FTC Guides and Product Representation for Sellers

In the fine jewelry industry, romance and beauty drive consumer emotion, but statutory law governs the counter.

Every time a sales professional describes a center stone, quotes metal purity, or explains an appraisal to a customer, their words are governed by federal regulations: specifically, the Federal Trade Commission (FTC) Guides for the Jewelry, Precious Metals, and Pewter Industries (codified under 16 CFR Part 23).

The FTC Guides are not optional industry suggestions; they are the federal benchmark for what constitutes deceptive, unfair, and illegal trade practices under Section 5 of the FTC Act. When an associate misrepresents a lab-grown diamond as “natural,” fails to disclose that an emerald has been fracture-filled with resin, quotes a misleading gold karatage, or tells a client that a $4,000 ring “appraises for $9,000,” they expose themselves and their employer to civil penalties, consumer restitution lawsuits, and enforcement actions coordinated by state Attorneys General and the Jewelers Vigilance Committee (JVC).

True luxury sales professionals take deep pride in complete legal compliance. Clear, transparent, and accurate product representation does not diminish perceived value. It elevates the jeweler above deceptive competitors and establishes unshakeable consumer trust.

This masterclass details the legal standards governing diamond origins, gemstone treatments, precious metal markings, and counter appraisals, equipping floor teams with the definitive compliance manual for counter sales.

1. Earth-Mined Diamond Unqualified “Diamond” • Formed Naturally in the Earth • 100% Pure Crystallized Carbon • Default Legal Definition • “Natural” / “Real” / “Mined” Zero Qualification Required

2. Laboratory-Grown Man-Made / Created Diamond • Identical Optical/Chemical Carbon • HPHT or CVD Factory Synthesis • MUST Use: “Lab-Grown”, “Lab-Created” • NEVER Call “Natural” or “Real” Mandatory Clear Descriptor

3. Diamond Simulant Cubic Zirconia, Moissanite • Different Chemical Composition • Simulates Visual Appearance Only • NEVER Call “Diamond” • “CZ”, “Synthetic Moissanite” Not a Diamond Mineral

Figure 1: FTC 16 CFR Part 23: The Diamond Nomenclature Spectrum. Federal regulations establish rigid disclosure categories for diamonds, requiring immediate, clear qualification for laboratory-grown stones and strictly prohibiting calling simulants diamonds.

1. Diamond Nomenclature & Origin Disclosures (§ 23.25)

Under 16 CFR § 23.25, the FTC establishes strict rules regarding how diamonds may be represented at retail:

Regulatory Ethics

The Unqualified Word “Diamond”

– The Statutory Baseline: It is unfair or deceptive to use the word “diamond” alone, without qualification, to describe any product that was not formed completely naturally in the earth.
– When an associate or price tag simply states: “1.50-carat Diamond Solitaire,” the law presumes and mandates that the stone is an earth-mined, natural diamond.

Laboratory-Grown Diamonds (§ 23.25(b))

When selling diamonds manufactured via High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD), the associate and store must comply with the following mandates:
1. Mandatory Qualifying Words: The stone must be immediately preceded by one of three approved descriptors:
– “laboratory-grown diamond”
– “laboratory-created diamond”
– “[Manufacturer name]-created diamond” (e.g., “Chatham-created diamond”)
2. Prominence Standard: The qualifying words must appear with equal conspicuousness and prominence as the word diamond. They cannot be buried in micro-print, hidden on the back of an appraisal, or omitted during verbal presentations.
3. Strictly Prohibited Words: An associate must never describe a lab-grown diamond as “natural,” “real,” “genuine,” or “earth-born.” While chemically and optically a diamond, it is not natural.

Diamond Simulants (§ 23.20)

Materials like Cubic Zirconia (zirconium dioxide) or synthetic Moissanite (silicon carbide) merely simulate the appearance of a diamond but possess completely different chemical, physical, and optical properties.
– It is illegal to refer to a simulant as a diamond (e.g., “Russian Diamond” or “Moissanite Diamond” is illegal).
– They must be clearly identified by their correct mineral or trade name: “Cubic Zirconia” or “Synthetic Moissanite.”

Gold (§ 23.3 – 23.4) 10K Statutory US Minimum • 10K = 41.7% pure gold • 14K = 58.3% pure gold • 18K = 75.0% pure gold • 24K = 99.9% pure gold Under 10K ≠ “Gold”

Platinum (§ 23.6) 950 vs 500 Alloy Rules • 950 Plat = 95% pure • 900 Plat = 90% pure • 500-850: Must disclose both metals (500Plat/500Irid) Under 500 ≠ “Platinum”

Silver (§ 23.5) Sterling Benchmark • Sterling = 92.5% silver • Coin Silver = 90.0% silver • Stamped “925” or “Ster” • 4 parts/1000 tolerance Mandatory Quality Mark

Vermeil (§ 23.4(b)) Heavy Gold Electroplate • Base MUST be 925 Sterling • Coating MUST be 10K+ Gold • Thickness ≥ 2.5 Microns (100/1,000,000 inch) Three-Part Legal Standard

2. Precious Metal Marking & Fineness Laws (§§ 23.3–23.8)

Precious metals are governed by the National Stamping Act (15 U.S.C. §§ 294–300) and FTC Guides. Sales associates must understand stamping fineness and legal tolerances:

1. Gold (§§ 23.3 – 23.4)

– The 10-Karat Rule: In the United States, an item cannot be described or stamped as “gold” if it is less than 10 karats (41.7% pure gold). Anything less (e.g., 9K or 8K, which is legal in the UK and Europe) cannot be represented as gold in US retail; it must be labeled “gold alloy under 10K” or base metal.
– Trademark Stamping Rule: Under federal law, if a piece of jewelry bears a quality mark (e.g., “14K”), it must legally bear a registered trademark or maker’s mark immediately adjacent to identify the manufacturer responsible for the assay.

2. Platinum (§ 23.6)

– 950 Platinum: At least 950 parts per thousand (95%) pure platinum. May be marked simply “Platinum” or “Plat.”
– 900 Platinum: At least 900 parts per thousand pure platinum (plus 50 parts other Platinum Group Metals). Marked “900 Plat.”
– 500 to 850 Platinum Alloys: Under FTC rules, an item with 500 to 840 parts platinum may only be referred to as platinum if the other alloying metal is also disclosed (e.g., “585 Plat / 415 Co” or “500 Plat / 500 Irid”).
– Under 500 Parts: Any item containing less than 500 parts per thousand pure platinum cannot use the word platinum at all.

3. Vermeil (§ 23.4(b))

Vermeil is one of the most frequently misrepresented metals at commercial counters. An item is legally “Vermeil” only if it meets a strict three-part statutory test:
1. The base metal must be Sterling Silver (92.5% pure) throughout.
2. The coating must be at least 10-karat gold.
3. The coating thickness must be at least 2.5 microns (100 millionths of an inch). If gold is plated over brass, copper, or stainless steel, calling it “vermeil” is illegal.

FTC GEMSTONE TREATMENT DISCLOSURE FRAMEWORK
16 CFR § 23.22 Standard

The Mandatory Disclosure Rule: It is unfair or deceptive to fail to disclose that a gemstone has undergone any treatment if any of the following three conditions apply:

1. The Treatment is Non-Permanent: If the treatment can change, degrade, or reverse over time under normal wear (e.g., dyed jade, surface-coated topaz, or fracture-filled diamonds).

2. The Gemstone Requires Special Care: If the treatment creates vulnerability to standard cleaning procedures, heat, chemicals, or ultrasonic tanks (e.g., cedarwood oil or resin in emeralds which dissolves in steam cleaners; fracture-filled rubies).

3. The Treatment Significantly Affects Market Value: If an untreated gemstone of similar appearance commands a substantially higher price in the market (e.g., unheated Burma ruby vs lead-glass filled ruby; heat-treated sapphire vs unheated sapphire; irradiated blue diamond).

The Written Invoice Mandate: FTC rules mandate that treatment disclosures must be made verbally at counter AND in writing on the client’s sales receipt.

Figure 3: FTC 16 CFR § 23.22 Gemstone Treatment Disclosure Framework. Statutory requirements compelling verbal and written disclosures based on treatment permanence, special cleaning care requirements, and market valuation impacts.

—

3. Gemstone Treatment Disclosures (§ 23.22)

In colored gemstones, artificial enhancement is common (e.g., standard heat treatment in 95%+ of sapphires). However, under 16 CFR § 23.22, the FTC enforces a Three-Part Test:

If a treatment is non-permanent, requires special cleaning care, or significantly affects market value, disclosure is legally mandatory.

Critical Showroom Treatment Protocols:

1. Lead-Glass Filled Rubies (Composite Rubies): Heavily fractured corundum infused with lead glass. These stones dissolve and turn white if exposed to standard jeweler’s pickle, lemon juice, or household cleaners. Describing them simply as “rubies” is a direct FTC violation; they must be identified as “composite ruby,” “lead-glass filled ruby,” or “manufactured glass-filled corundum.”
2. Oiled / Resin-Treated Emeralds: Over 90% of fine emeralds contain surface-reaching fractures filled with cedarwood oil or synthetic resins. Associates must inform the client that the stone must never be placed into an ultrasonic tank or steam cleaner.
3. Irradiated / High-Pressure Treated Diamonds: Diamonds treated to alter color (e.g., HPHT or electron bombardment) must be clearly designated as “treated diamond” on all sales documents.

DECEPTIVE PRICING & APPRAISAL PROHIBITIONS
FTC & JVC Guardrails

The “Appraisal Equity” Closing Lie:
Banned Sales Pitch: “Buy this diamond today for $5,000, and our certified appraiser will give you an appraisal document for $10,000, so you’re instantly doubling your money!”

Why This is Illegal Consumer Fraud: Under FTC Deceptive Pricing Guides (16 CFR Part 233) and state unfair trade practice statutes, quoting an inflated appraisal value to create a false impression of savings or instant profit is actionable fraud. A consumer cannot sell the item for $10,000; the true retail market value is the price they just paid.

The Compliant Appraisal Purpose: Insurance appraisals represent Estimated Retail Replacement Cost for casualty loss indemnity under a homeowner’s insurance policy, accounting for potential inflation, custom fabrication labor, and retail markup. It is NOT cash value.

The Professional Counter Script: “This appraisal document is prepared specifically for your insurance company to ensure full replacement coverage in the event of loss or theft. It reflects the cost to reconstruct this piece from scratch, not a cash resale value.”

Figure 4: JVC Deceptive Pricing & Inflated Counter Appraisal Prohibitions. Pitching inflated insurance appraisals as “instant equity” or investment profits violates FTC deceptive advertising guides and state consumer fraud laws.

4. Deceptive Pricing & Inflated Counter Appraisals

One of the most persistent abusive practices in commercial retail is using inflated in-house appraisals as closing deploy.

Under FTC Deceptive Pricing Guides (16 CFR Part 233), an appraisal must represent a genuine, objective valuation based on real marketplace sales. When a retailer promises an appraisal document at twice the sales price, they are engaging in deceptive marketing.

The True Purpose of a Counter Appraisal

– An insurance appraisal is a legal indemnity document designed to enable an insurance underwriter (e.g., Jewelers Mutual) to replace the piece with one of like kind and quality in the event of loss, theft, or fire.
– It includes retail markup, bench labor, and a margin for future precious metal price inflation.
– The Golden Counter Rule: Never sell an appraisal as an “investment return.” Present it strictly as an insurance protection service.

COUNTER INVOICE COMPLIANCE CHECKLIST
Daily POS Audit

□ 1. Diamond Origin Verified: If lab-grown, the receipt explicitly states “Laboratory-Grown Diamond” or “Lab-Created Diamond” in equal font size.

□ 2. Metal Karatage & Fineness: Precious metal purity is explicitly recorded (e.g., “14K White Gold”, “950 Platinum”). Never list simply “white gold” without karatage.

□ 3. Gemstone Treatments Disclosed: All known treatments (heat, oil, fracture filling) are clearly documented on the printed invoice along with special care instructions.

□ 4. Total Diamond Carat Weight (CTTW) Disclosure: If quoting total weight across multiple stones, the receipt states “Total Weight” or “CTTW” and adheres to FTC fraction tolerances (e.g., a 3/4 ct piece must fall between 0.69 and 0.81 ct).

□ 5. Appraisal Disclaimers Attached: All accompanying appraisal paperwork clearly states that values represent Estimated Retail Replacement Value for insurance purposes only.

5. Summary: Essential Compliance Rules for Every Counter Professional

1. Unqualified “Diamond” Means Natural: Never use the word diamond alone unless it came out of the ground.
2. Clear Lab-Grown Qualification: Always use “laboratory-grown” or “laboratory-created” with equal prominence; never describe lab-grown diamonds as “real” or “natural.”
3. Disclose All Treatments in Writing: Non-permanent treatments, special care requirements, and value-altering enhancements must appear on the sales receipt.
4. Know Your Metal Laws: 10K is the statutory gold minimum in the US; 950 and 900 are platinum standards; vermeil requires 925 sterling base with 2.5 microns of 10k+ gold.
5. Never Sell Inflated Appraisals: Frame appraisals strictly as insurance replacement documents, never as instant profit or investment equity.
