This investigation reveals a sophisticated international smuggling ring trafficking counterfeit diamonds with forged certificates. The case underscores the critical need for enhanced verification protocols and cross-border cooperation to protect consumers and maintain trust in the gemstone industry.

Synthetic diamonds passed off as authentic, falsified Belgian certificates, and jewelry pieces sold for up to 55,000 dirhams each… The National Customs Brigade has uncovered a sprawling smuggling network operating between Morocco, Belgium, and several African countries.
The National Customs Brigade has recently intensified its investigations into an international network specializing in smuggling counterfeit precious stones, particularly fake diamonds integrated into local manufacturing and distribution chains, according to well-informed sources.
It all began with a series of alerts signaling the unusual presence of heavily discounted diamonds in the markets of Casablanca, Rabat, and Marrakech. Stones of impeccable brilliance, sold as authentic in reputable boutiques and even on well-established e-commerce platforms, but beneath the sparkle lay deception.

Initial investigations uncovered a well-organized system: batches of synthetic diamonds were transiting from Belgium and some African countries to Morocco, before being injected into jewelry production circuits. The smugglers allegedly relied on fake quality certificates issued by a Belgian certification office, initially intended for other sectors, notably agri-food.
These perfectly imitated documents gave legitimacy to shipments of counterfeit stones. Once introduced into the country, they were used by local goldsmiths to manufacture rings, bracelets, and necklaces subsequently sold in high-end retail outlets. Some pieces reached prices of up to 55,000 dirhams, despite the derisory real value of the embedded stones.
In coordination with regional teams, National Brigade agents managed to trace the trail thanks to suspicious invoices for batches of jewelry containing counterfeit diamonds. These documents helped identify the distribution circuits and intermediaries involved in the “legalization” of the goods through direct sales chains.

The investigation also relies on the work of a central analysis unit under the customs administration, which traced the journey of the stones from their entry into the territory to their display in the country’s most coveted shop windows. Several manufacturing units are alleged to have circumvented legal obligations requiring the keeping of accounting records for raw materials, similar to the system in place for gold.
Part of the scandal lies in the difficulty of distinguishing synthetic diamonds from natural stones. In the absence of specialized laboratories in Morocco, even some industry professionals are believed to have been duped.
This technical ambiguity allowed traffickers to exploit market trust and flood the country with fake stones, sometimes sold for more than 25,000 dirhams per carat, while their real cost does not reach half that amount.
