Diamond Dealer in Antwerp Since 1987
We are proud of our heritage of excellence and our dedication to providing the highest quality certified loose natural diamonds from the heart of the Antwerp diamond district.
Our Story
Your Trusted Diamond Dealer in the Heart of Antwerp
As a trusted diamond dealer in Antwerp since 1987, Diamantwerp has grown from a modest trading operation in the famous Pelikaanstraat into one of Belgium's most respected sources for certified loose natural diamonds.
Our founder began with a simple conviction: that everyone deserves access to beautiful, certified diamonds — graded by GIA, HRD Antwerp, and IGI — without the premium markup of fancy retail stores. That mission hasn't changed in nearly four decades.
What started as wholesale-only evolved into something bigger. Today, we're the diamond dealer Antwerp residents and international buyers alike turn to — whether they're professional jewellers or first-time buyers searching for the perfect stone. We work directly with cutters and suppliers, cutting out middlemen and passing savings of up to 75% directly to you.
Every diamond in our collection is evaluated against the four C's: cut, colour, clarity, and carat weight — the universal framework for understanding diamond quality.
