GDJ · the open standard

One integration. The whole trade.

The diamond and jewelry trade has never had a shared language. We published one — and we are building it to be the rails the whole industry runs on.

A founder answers — usually the same day.

The network, at a glance

Everyone, one language.

Stores, suppliers, labs, workshops, carriers and the apps in front of them — all speaking the same standard, with a registry that says who is who.

Write it once

One integration reaches every firm on the network — stores, suppliers, labs, workshops. Not one bespoke connection per counterparty, forever.

Every message is signed

Who sent what, when, and what it said — settled by signature instead of by email archaeology. Disputes get shorter.

It won't break under you

Versioned like infrastructure: dated releases, strict compatibility rules, and no breaking change arriving on a Tuesday afternoon.

Nobody can raise the rent

It is published in the open, with a public conformance suite, and anyone may implement it — including firms that compete with us. That is the point of a standard.

Built to be the rails the whole trade runs on — not a private network you rent from us.

Who builds on it

Three kinds of builder.

If your software touches a stone, a piece, or the money for either, it belongs on the network.

Store & counter software

Point-of-sale, inventory, and repair systems that want live stock, quotes and order status from the whole trade instead of one supplier's feed.

Supplier, lab & workshop systems

Inventory and grading platforms that want their stock and their certificates to reach every buying store without another portal to keep up to date.

Buying apps & tools

Anything a jeweler or a trade buyer opens to find a stone, commission a piece, or check where an order stands.

How access works

Everyone passes the same suite.

Tell us what you're building. If it fits, you get the full specification and a sandbox — then you prove it against the conformance suite like everyone else on the network.

Request access.

The specification, the sandbox, and the conformance suite are handed over after we’ve talked — a short conversation, not a procurement cycle.

  • You keep your own product, your own customers, your own roadmap.
  • No fee to implement the standard. No exclusivity, ever.
  • Certified implementations are listed on the network registry.

We use this only to review your application — no list, no drip campaign. See the privacy policy.

An industry deserves one set of rails.

We are building them in the open, and we would rather you built on them than around them.
