Contact your Diamond Dealer in Antwerp

Yes. Every diamond we sell is independently graded by GIA, HRD or IGI — the three most respected gemological laboratories worldwide — and the original certificate ships with the stone. Your payment is processed on a secure checkout, and delivery is fully insured door-to-door.

Diamantwerp has been registered in Antwerp's diamond district since 1987. We are not a dropshipping middleman — every stone passes through our hands in Antwerp before it ships.

All three. Each diamond in our inventory is independently graded by one of the three top-tier gemological laboratories, and you can filter by lab on the shop page.

Read the detailed differences and strengths of each lab here: GIA certified diamonds, HRD certified diamonds, and IGI certified diamonds. For high-value stones (typically >1 carat), GIA is the global benchmark; for European buyers HRD is equally trusted; IGI is the strongest choice for lab-grown and increasingly for natural stones as well.

Browse our live certified inventory, filter by shape, carat, colour or clarity, and add the diamond you want to your cart. Checkout accepts card, Bancontact and bank transfer — orders paid by bank transfer receive a 1% discount.

Absolutely — this is what we do best. Tell us your budget, shape preference and the purpose of the stone (for example an engagement ring), and we'll shortlist 2 to 3 certified options with honest trade-offs explained. Our recommendations are independent — we don't push any single stone.

To get a head start, read our guide to the 4 C's (cut, colour, clarity, carat) and our diamond engagement ring guide. These cover the decisions most customers find hardest, in plain language.

Yes. Our online inventory shows what we have in stock today, but through our network in the Antwerp diamond district we can source virtually any certified natural diamond to your specifications — shape, carat, colour, clarity and budget.
