KYC (know-your-customer) in the jewellery trade refers to the body of customer-identification, verification and due-diligence obligations imposed on dealers in precious metals and stones under anti-money-laundering (AML) and counter-terrorist-financing (CTF) regulation. The obligations are jurisdiction-specific in detail but globally consistent in framework, and they have grown substantially in scope and enforcement intensity over the past two decades as international regulators have identified the high-value, portable, fungible character of gemstones and gold as a money-laundering vulnerability.

Regulatory framework

The international template is set by the Financial Action Task Force (FATF), an inter-governmental body founded in 1989 whose Forty Recommendations are the world standard for AML and CTF compliance. Recommendation 22 specifically designates dealers in precious metals and stones (DPMS) as a category of designated non-financial business and profession (DNFBP) subject to AML obligations. National regulations transpose the FATF framework into binding law.

Major jurisdictions and their primary KYC frameworks include: the United States (the Bank Secrecy Act as amended by the USA PATRIOT Act, with FinCEN as the regulator and the Anti-Money Laundering Act of 2020 expanding scope); the European Union (the Fourth, Fifth and Sixth Anti-Money Laundering Directives, transposed into member-state law); the United Kingdom (the Money Laundering, Terrorist Financing and Transfer of Funds Regulations 2017 and the High Value Dealer regime under HMRC); Canada (the Proceeds of Crime (Money Laundering) and Terrorist Financing Act administered by FINTRAC); Australia (AUSTRAC); Switzerland (the Anti-Money Laundering Act administered by FINMA); the United Arab Emirates (Federal Decree-Law No. 20 of 2018, with the Ministry of Economy supervising DNFBPs); and Hong Kong and Singapore equivalents.

Threshold-triggered obligations

Most jurisdictions impose KYC and reporting obligations on cash transactions above a defined threshold. Common thresholds include US$10,000 in the United States, EUR 10,000 in the European Union (lowered to EUR 3,000 for cash purchases in some member states), £10,000 in the United Kingdom, and CAD 10,000 in Canada. Above the threshold, a dealer must collect and verify customer identification (passport or government-issued ID, address verification, beneficial-owner identification for corporate customers), record the transaction, and in some jurisdictions report it to the relevant financial intelligence unit.

Below the threshold, simplified due diligence may apply, but the dealer remains responsible for not structuring transactions to avoid the threshold (splitting a US$15,000 sale into two US$7,500 cash transactions on consecutive days, for example, would itself be a reportable suspicious activity).

Customer due diligence

Standard customer due diligence (CDD) requires identification, verification, beneficial-ownership disclosure for legal persons, and an understanding of the customer's source of funds and source of wealth. Enhanced due diligence (EDD) applies to politically exposed persons (PEPs), high-risk jurisdictions, and complex or unusual transactions. EDD typically requires senior-management approval, more thorough source-of-funds verification, and ongoing monitoring of the relationship.

Identification documents must be retained for a defined period (commonly five years from the end of the business relationship) and must be available for inspection by the regulator. Many jurisdictions require electronic verification through approved identity-verification services for higher-value transactions or where physical presence is not possible (online sales, international wire transfers).

Suspicious activity reporting

All major jurisdictions impose an obligation to report suspicious activity to the national financial intelligence unit. Suspicious indicators in the jewellery trade include: cash transactions structured to avoid thresholds; unusual or unexplained source of funds; reluctance to provide identification; purchase of high-value, easily portable items by persons inconsistent with the apparent profile; rapid resale of items purchased for cash; complex corporate or trust structures with no apparent commercial rationale; transactions involving high-risk jurisdictions; and beneficial owners who cannot be identified.

Reports are filed through national systems (SAR to FinCEN in the United States, SAR to the National Crime Agency in the United Kingdom, STR to FINTRAC in Canada). Tipping-off provisions prohibit the dealer from informing the customer that a report has been made.

Operational implementation

Compliance jewellers typically implement KYC through a written compliance programme covering: a designated AML officer; documented customer-identification procedures with electronic verification; staff training on suspicious-activity recognition; record-keeping systems retaining identification documents and transaction records for the required period; risk-assessment procedures for new customers and new product lines; and periodic independent review or audit.

Industry associations, including the Responsible Jewellery Council, the World Diamond Council, the World Gold Council, and the Jewelers of America, publish model compliance programmes and training materials. Larger firms typically retain external compliance counsel; smaller firms often work from association templates.

Sanctions and OFAC screening

Beyond AML, jewellery dealers must screen transactions against international sanctions lists, particularly the OFAC SDN list in the United States, the EU consolidated sanctions list, and the UK HM Treasury sanctions list. Burmese ruby and jadeite, Russian diamonds (depending on date and jurisdiction), and various individual sanctioned persons present specific compliance risks. Screening must be conducted on customers, their beneficial owners, the source country of goods, and the route of any wire transfer.

Penalties

Non-compliance carries substantial penalties. In the United States, FinCEN civil penalties can reach hundreds of thousands of dollars per violation; criminal prosecution is possible for wilful violation. The UK HMRC can impose unlimited civil penalties on high-value dealers and refer cases for criminal prosecution. The European Union framework provides for penalties up to ten percent of annual turnover or EUR 5 million, whichever is higher. Reputational damage from public enforcement actions is often more costly than the financial penalty itself.

Trade implications

For the working dealer, KYC has substantially reshaped the international trade. Cash transactions above thresholds have shifted to bank wire and letter-of-credit; new-customer onboarding has become more time-consuming; private-client and trade-show transactions require documentation systems that older trade culture did not anticipate; and jurisdictional differences create complexity in cross-border supply chains. Compliance is no longer optional, and modern dealers structure their operations around identification, record-keeping, and screening as default practice.
