Diamantwerp

Diamantwerp is a Belgian diamond dealer based at Pelikaanstraat 62 in the heart of the Antwerp diamond district, an area that has served as a global diamond trading hub for more than five centuries. The business describes itself as operating since 1987, when it began as a modest trading operation in the same street, and it has since grown into one of Belgium's better-known sources for certified loose natural diamonds. Its core proposition is straightforward: sell independently graded stones directly from the Antwerp trade, cutting out the retail middlemen that traditional high-street jewellers rely on, and pass the resulting savings to buyers. The company positions itself at the intersection of wholesale and retail. It serves both professional jewellers sourcing stones for their own customers and private buyers — including first-time buyers — looking for a single certified diamond. Every stone in its collection is graded by one of the three major laboratories it names: the Gemological Institute of America (GIA), HRD Antwerp and IGI. Diamonds are evaluated against the industry-standard 4 C's — cut, colour, clarity and carat weight — and the company publishes educational material on that framework to help buyers compare stones objectively. It also states that its diamonds are conflict-free and Kimberley Process compliant, and that it is a member of the Antwerp World Diamond Centre (AWDC), the umbrella body that governs certified diamond trading in the city. Diamantwerp's marketing leans heavily on the "Antwerp advantage." It notes that more than 80% of the world's rough diamonds and roughly half of polished diamonds pass through the Antwerp district, and argues that buying directly from that ecosystem gives customers access to source pricing. The company claims prices up to 75% below those of traditional high-street jewellery stores, and advertises fast fulfilment, stating that 95% of orders are delivered next day, either by personal delivery or insured shipping. Its collection is organised primarily by diamond shape — round brilliant, oval, princess, cushion, emerald, pear, radiant, marquise, asscher and heart — with each shape presented as certified and ready to ship. The business remains privately held and does not disclose a parent company or ownership structure in its public materials. Its self-reported figures include more than 37 years of experience and 10,000 happy clients, alongside the 75% below-retail and 95% next-day-delivery claims. As a specialist dealer rather than a jewellery manufacturer, Diamantwerp's brand identity rests on certification, provenance and price transparency rather than on proprietary designs or a signature retail experience.

Diamantwerp traces its origins to 1987, when its founder established a modest diamond trading operation on Pelikaanstraat in Antwerp, the street at the centre of the city's historic diamond district. The founding conviction, as the company describes it, was that buyers should have access to beautiful, certified diamonds graded by independent laboratories without paying the premium markups charged by fancy retail stores. In its early years the business operated on a wholesale-only basis, trading stones within the Antwerp trade rather than selling to the public. Over the following decades the company grew within the Antwerp diamond ecosystem, a district that has been the world's leading diamond centre for more than 500 years and through which, by the company's account, more than 80% of the world's rough diamonds and about half of all polished diamonds still pass. Operating from Pelikaanstraat 62, Diamantwerp worked directly with cutters and suppliers, a sourcing model it says allows it to cut out middlemen and pass savings of up to 75% on to customers. It became a member of the Antwerp World Diamond Centre (AWDC), the industry body that oversees certified diamond trading in the city, and aligned its inventory with the grading standards of the Gemological Institute of America (GIA), HRD Antwerp and IGI. At some point the wholesale-only model evolved. The company began serving private buyers as well as professional jewellers, positioning itself as the dealer that both Antwerp residents and international customers turn to when searching for a certified stone — whether a trade buyer sourcing inventory or a first-time buyer looking for a single diamond. It built out an educational content offering around the 4 C's — cut, colour, clarity and carat weight — the grading framework introduced by the GIA in the 1950s and now used by all major laboratories, to help customers compare stones objectively and avoid overpaying. By the mid-2020s Diamantwerp presented itself as a nearly four-decade-old business with more than 37 years of experience and 10,000 clients, selling certified loose natural diamonds online and by direct arrangement, with 95% of orders delivered next day by personal delivery or insured shipping. Its collection is organised by diamond shape, from round brilliant to heart, and it markets itself on transparency, ethical sourcing and Kimberley Process compliance. The company remains privately held and does not publicly disclose its ownership or a parent group.
