GIA certified natural diamonds, wholesale.
Independently graded natural diamonds with full GIA documentation, priced for the European trade and shipped from Antwerp.
What GIA certification means
The Gemological Institute of America created the modern 4Cs (cut, colour, clarity, carat) and remains the most trusted grading laboratory in the natural diamond trade. A GIA report is not an appraisal — it is an independent scientific evaluation of the stone's measurements, proportions and quality characteristics. For wholesale buyers, a GIA-certified stone is the industry benchmark: consistent, comparable and instantly recognised by every reputable retailer and secondary-market house in the world.
How we verify and grade
Every natural diamond we supply arrives with an original GIA report and a matching laser inscription on the girdle. On receipt we cross-check the stone against its certificate — measurements, weight, fluorescence and clarity plot — before it enters our inventory. Stones are stored in sealed, tamper-evident parcels and travel with their paperwork through the full chain of custody.
How wholesale pricing works
Natural diamond wholesale pricing tracks the Rapaport list adjusted for current market conditions, then discounted from list based on shape, colour, clarity and cut grade. As an Antwerp-registered wholesaler we buy directly and apply true trade margins — not retail markups — so our per-carat pricing is suitable for jewellers who need to build their own margin on top. Volume breaks apply on parcel orders and repeat programmes.
Shipping across Europe
In-stock GIA natural stones ship insured from Antwerp within one business day. We handle EU intra-community VAT documentation, customs paperwork for non-EU deliveries and secure courier handoff. Bespoke sourcing to a specific certificate — for example a matched pair or a specific fancy colour — is available within seven business days.
