Certification & Trust
Two questions, answered before you ask them.
Is the stone real and as-graded? And will you actually receive it? Everything here exists to answer one or the other — in writing, and open to your own checking.
Why it's safe
Transparency, where the trade usually offers secrecy.
Independently certified
Every stone carries a GIA coloured-diamond report — and we invite you to verify the report number yourself at GIA.edu before you commit to anything.
You see it first
View any stone in person in Antwerp or by secure video, with time to decide. Nothing is rushed.
Secured end to end
Payment through escrow; delivery by insured, specialist couriers. Full provenance and origin documentation with every stone.
Real people, real address
A named Antwerp house you can meet — not an anonymous inbox.
Certification
An independent report on every stone — verified by you.
Every stone we present carries an independent GIA coloured-diamond report (and, where relevant, HRD Antwerp). Before any money moves, you verify the report number yourself, directly on GIA’s own website. We’ll walk you through reading it — hue, tone, saturation, and whether the colour is natural in origin.

Independent verification is the point of certification. If a seller discourages it, walk away.
Natural colour of origin
Natural, never treated — and always disclosed.
With fancy colour, the origin of the colour is everything: natural and treated stones can differ many times over in value. We deal in natural colour, confirmed on the report, and we will always tell you plainly what a stone is. No grade is ever implied that a certificate does not state.
Provenance & sanctions
Documented origin, done properly.
Every stone is accompanied by origin documentation and, where applicable, Kimberley Process / G7 certification confirming it is not of Russian origin. Provenance is part of the price of doing this properly. Slot: exact provenance / KP-G7 language to confirm with the seller
Payment
Funds move through escrow.
Payment is made through escrow — not wired into the unknown. Every step is set out in writing before you commit, so you always know what happens next and when.
Delivery
Insured, specialist couriers.
Stones are delivered by insured, specialist couriers, with full documentation. Slot: confirm the exact logistics partners used (houses such as Malca-Amit and Brink's are typical of the trade).
Viewing
You see it first.
View any stone in person in Antwerp or by secure video, with the time you need to decide. Nothing is rushed, and nothing is presented that you didn’t ask for.
We source and advise on quality and provenance; we do not provide investment advice, and past market performance is never a guarantee of future value.
Private consultation
When you're ready, we'll talk.
No obligation. A confidential conversation, usually by video, to understand your brief.
