Why is Antwerp known as the diamond capital of the world?

Antwerp has been the world's leading diamond hub since the 16th century, when declining harbour trade in Bruges redirected the global diamond trade to its port. Diamond cutting techniques, first developed in Bruges in the mid-15th century, were refined by craftsmen in the Kempen region, giving Antwerp an early technical edge that shaped the city's identity for centuries. Today, roughly 80% of the world's rough diamonds still pass through Antwerp, and the city's cutting and grading standards remain a global benchmark. That heritage directly informs how lab-grown diamonds are designed and finished here: the same precision applied to mined stones for centuries now applies to IGI-certified lab-grown diamonds. Antwerp's reputation was never built on stone origin; it was built on cut quality, consistent grading, and accumulated craft knowledge. For buyers, that means the Antwerp provenance on a lab-grown piece carries the same technical weight it always has.
