Wholesale diamond supplier based in Antwerp.
Certified lab-grown and natural diamonds, sourced and shipped from the world's oldest diamond trading centre — direct to jewellers and retailers across Europe.
Why Antwerp matters
Antwerp has been the centre of the international diamond trade for more than five centuries. Roughly 80% of the world's rough diamonds and half of all polished stones still move through the city's four exchanges. Trading in Antwerp means access to the deepest inventory pool in the industry, the tightest polishing standards and a regulatory framework — HRD Antwerp, the Antwerp World Diamond Centre, Belgian customs — that keeps every transaction documented and traceable.
Our office and credentials
Medina Diamonds is registered in Antwerp and works inside the local trade network. We source directly from cutting factories and certified rough suppliers, which lets us skip the layers of middlemen that inflate wholesale prices elsewhere. Every stone we handle passes through independent gemological grading — IGI or HRD Antwerp for lab-grown, GIA for natural — before it reaches your invoice.
Who we serve
We supply independent jewellers, design studios, multi-brand retailers and gem traders in 29+ European countries. Our clients typically stock both product lines — natural diamonds for bridal and heritage pieces, lab-grown for fashion, volume and price-led collections — under one wholesale account with consolidated shipping and paperwork.
Sourcing and certification process
Every request starts with your specification: shape, carat range, colour, clarity and target price. We match against 3,000+ carats of live inventory or source to order from our polishing partners in Antwerp and India. Certificates travel with the stone, and in-stock orders ship insured within one business day.
