GEMERCEL

The Gemercel network

One partner.

Dealers, cutters, labs, and makers behind one firm, one invoice — every stone verified.

Your customers see you. You see one partner.

✓✓✓✓YOUR STOREDEALERLABCASTERBUYERevery handoff verified · every stone answers to one call

What that buys you

One call settles it.

Sourcing, terms, verification, and problems — all answerable by one firm.

One invoice

Stones from five sources arrive as one delivery, one invoice, one person to call when anything's off.

RFQ, in writing

Tell us “2ct oval, F–G, VS+, by Friday.” Comparable quotes come back in writing.

Terms that can't drift

Every order settles against terms both sides agreed in writing — no he-said-she-said.

Verification you can show

A custody trail your customer can check at the counter, not just take on faith.

Problems with due process

If something's wrong: raise it, resolve it, documented end to end. No ghosting.

Trade services, same rails

Memo, repairs, and appraisals move between firms with the same paper trail as an order.

Every side of the counter

What each partner gets.

A network only holds if it's worth being on from every side. Here's the deal each side is offered.

Trust, on paper

Show, don't promise.

Certificate cross-check, intake inspection, custody trail — proof for the counter.

Nobody joins without passing something.

A supplier is screened and its certificates cross-checked with the issuing lab before a single stone is listed. A workshop sends a sample piece to our bench and meets a six-point checklist before it is ever handed a job.

That gate is the whole reason your store can sell goods it didn’t source itself with a straight face.

How suppliers qualifyHow workshops qualify

Under the hood

We published the standard.

The plumbing is GDJ, the Global Diamond Jewelry Protocol — published open for the whole trade. For those who ask.

THE OPEN STANDARDone shared languageTHE REGISTRYevery firm known · every message signedSTORE SOFTWARESUPPLIER SYSTEMSBUYER APPSLABS & GRADERSSHIPPING & COVERWORKSHOPSEVERY DEAL, THE SAME SHAPEDISCOVERQUOTEORDERSETTLESERVICEone integration · every participant

Open, or it doesn't count

The standard is published with a public conformance suite. Anyone can implement it — including our competitors. That's the point.

Networks you rent can raise the rent

Closed networks own your pipeline and price it back to you. An open standard means your relationships stay yours.

Signatures, not trust falls

Every message is signed against a live registry of who's who. “He said, she said” becomes “here's the signature.”

Versioned like infrastructure

Dated releases with strict compatibility rules — the network evolves without breaking the stores running on it.

Built to be the rails the whole trade runs on.

You never have to think about it. Your software vendor might want to.

For developers & partners

One call. One partner.
