Rough Stone, Clean Money

A diamond has no memory.

Once it is cut, polished, and set into a ring, its appearance reveals nothing about where it came from, who paid for it, or what that money was doing before it became a stone.

That absence of visible history is precisely what can make the diamond trade vulnerable to money laundering and terrorist financing.

The risk does not necessarily begin when the diamond reaches a jewellery store.

It can begin much earlier, at the point where the stone is extracted from the ground, and continue through every transaction that follows.

Where the Journey Begins

Somewhere in a region affected by conflict, a rough diamond is pulled from the ground.

In areas where illegal diamond trading has supported armed groups, the proceeds generated from these stones can become connected to criminal or terrorist financing before the diamond has travelled across a single border.

This makes the origin of the diamond an important part of the AML picture.

If businesses cannot establish where a diamond came from, who owned it, who sold it, and how the transaction was funded, the stone can enter the legitimate supply chain carrying risks that may remain hidden for years.

When the Diamond Changes Hands

The rough diamond begins moving between traders, exporters, importers, cutters, manufacturers, and other businesses.

According to FATF research conducted with the Egmont Group, vulnerabilities can exist throughout the diamond pipeline, including production, the initial sale of rough diamonds, cutting and polishing, jewellery manufacturing, and retail.

Every transfer creates another opportunity for the ownership, value, origin, or financial history of the diamond to become difficult to verify.

In a complex international supply chain, invoices can be manipulated, transactions can pass through multiple companies, and payments can move between several jurisdictions.

The more complicated the chain becomes, the harder it can be to understand the true story behind the transaction.

When a Rough Stone Gets a New Identity

The diamond eventually reaches a cutting and polishing centre, potentially in another country.

The transformation is significant.

A rough stone becomes a polished diamond with a substantially different appearance and potentially much greater commercial value.

This transformation can make the original history of the stone increasingly difficult to establish.

It can also create opportunities for fraudulent invoices, misleading descriptions, incorrect valuations, and transactions involving related companies.

Another concern is the commingling of legitimate diamond revenues with illicit proceeds.

When legitimate business income and criminal proceeds enter the same company accounts, identifying the source of individual funds can become considerably more difficult.

When the Diamond Becomes a Line in the Books

Eventually, the diamond may appear as nothing more than another entry in a company's accounting records.

At this point, the physical stone becomes less important than the financial activity surrounding it.

An unexplained increase in trading volume, transactions that do not correspond with the company's normal business activities, unusual payment patterns, unexplained relationships between counterparties, or transactions involving unexpected jurisdictions can all raise questions.

Supporting documentation also becomes critical.

A document may state where a diamond originated, but the document itself does not prove that the diamond actually came from that location.

This is where customer due diligence, transaction monitoring, beneficial ownership checks, and appropriate record keeping become essential.

From Diamond to Cash

The diamond eventually reaches the jewellery market.

High value goods such as diamonds can be attractive to criminals because significant amounts of value can be concentrated into small and portable items.

A legitimate customer may purchase a diamond for completely ordinary reasons.

However, where AML controls are weak, criminals may attempt to exploit purchases of valuable goods, cash transactions, weak customer due diligence, or inadequate record keeping to make illicit funds appear legitimate.

The receipt may look completely ordinary.

The financial activity behind that receipt may tell a very different story.

The Problem Is the Chain

At no individual stage does the diamond itself look suspicious.

It is first a rough stone.

It then becomes a cut diamond and eventually part of a piece of jewellery.

Each stage can appear to be a normal commercial transaction.

That is what makes the risk so challenging.

The vulnerability is not the diamond itself.

It is the chain of transactions, people, companies, jurisdictions, payments, and documents surrounding it.

A diamond can carry significant value while remaining relatively easy to transport.

Its physical appearance also cannot tell an investigator whether the documentation supporting its origin, ownership, and value is genuine.

For this reason, effective AML controls need to look beyond the product itself.

Businesses need to understand their customers, beneficial owners, counterparties, source of funds, transaction patterns, jurisdictions, pricing, and supporting documentation.

Someone Has to Remember

A diamond does not remember where it came from.

The industry has to remember for it.

That means maintaining reliable records, conducting appropriate customer due diligence, understanding beneficial ownership, monitoring unusual transactions, assessing source of funds and wealth where appropriate, and questioning transactions that do not make commercial sense.

The diamond industry is not inherently suspicious.

It is a legitimate global industry supporting thousands of businesses and workers.

However, like many high value industries, it can be exploited when controls are weak and transactions are not properly understood.

The real challenge for AML professionals is identifying when an ordinary looking transaction is actually part of a much larger financial story.

Because the stone cannot tell investigators where it came from.

The transaction should.
