Why Buy Diamonds in Antwerp?

Antwerp has been the diamond capital of the world for over 500 years. Today, more than 80% of the world's rough diamonds and 50% of polished diamonds pass through the Antwerp diamond district — making it the single most important centre for diamonds on the planet.

When you buy diamonds in Antwerp from Diamantwerp, you benefit from this centuries-old expertise and direct access to the global diamond supply chain. Our prices are up to 75% lower than traditional high-street jewellers because we operate directly from the heart of the Antwerp diamond district at Pelikaanstraat 62, cutting out expensive middlemen.

What Makes Our Diamonds Different

Every diamond we sell comes with an independent certificate from one of the world's three most respected gemological institutes: GIA (Gemological Institute of America), HRD Antwerp, or IGI (International Gemological Institute). These certificates verify the exact quality of your diamond based on the 4 C's — cut, clarity, colour and carat weight.

Whether you're a jeweller looking for wholesale loose diamonds in Antwerp or a private buyer searching for the perfect engagement ring diamond, our team of experienced diamond specialists will guide you through every step — from selection to delivery.
