“She wanted a kite-cut bezel. You had a round prong. She bought it online that night.”

Gemercel replaces the supplier list — not just the software.

Every supplier is screened and their certificates cross-checked before a stone is listed. Every workshop passes our bench and a six-point checklist before it is handed a job.

Under the hood it runs on GDJ — the Global Diamond Jewelry Protocol, an open standard we published for the whole trade. You never have to think about it.

The network story

Every side of the counter

Four ways in.

Whichever door you come through, what's yours stays yours.

Your customers, your designs, your margins — yours.

We stand behind your counter, not in front of it. Nothing on this network asks you to hand over the relationships you built.

The offer

Founding partners.

A limited first cohort, onboarded by hand — because white-glove doesn’t scale, and that’s the point.

01

Zero-inventory start

The whitelabel catalog goes live under your brand day one. Sell from our stock; buy what sells.

02

White-glove migration

We move your inventory, customers, and open memos ourselves. You point; we do the archaeology.

03

Founding pricing, locked

Your rate never rises while you stay.

04

A direct line

Founders answer, not a ticket queue.

The guarantee

If Gemercel hasn’t replaced at least three of your systems in 90 days, we’ll export everything and walk you back — free.

The risk of switching should be ours, not yours.

No contract until you’ve seen your own inventory inside it.

Founding partners are first in line when the invite-only memo program reviews new stores.

The questions

Straight answers.

So what exactly is Gemercel — a software company or a supplier?
Both, on purpose. We stock lab and natural diamonds, cut custom shapes to order, run star melee programs, and manufacture finished jewelry through our own job-work network — and we built the software that runs your store on top of it. Your customers only ever see your brand.
Do I have to buy inventory to start?
No. The whitelabel catalog puts our live stock in your storefront and your counter under your name, at your margins. You buy a stone when a customer does. Your own inventory sits alongside it in the same case.
Can my customers tell Gemercel is behind it?
No — that's the whole point of whitelabel. The storefront runs on your domain with your name and branding, quotes and invoices carry your identity, and the jewelry ships as your work.
Do I have to run all that back-office software myself?
No — that's the point of a partner over a platform. You and your staff touch a handful of screens: the counter, your storefront admin, the showroom app, the client portal, and the Studio. The books, filings, purchase orders, and counts run on our side of the glass — you see results and reports, not modules.
How does the memo program work?
It's invite-only and deliberately limited — memo is trust, not a feature toggle. Ask about it on your demo; if it's a fit, we'll walk you through the review.
Do I have to drop my existing suppliers?
No. We're not exclusive and the platform isn't a walled garden — nothing locks you in. Most stores start by filling the gaps their current suppliers can't: custom shapes, melee programs, manufacturing overflow.
I supply stones, run a bench, or build software — can I join?
Yes, by application. Suppliers are screened and their certificates cross-checked with the issuing lab before anything is listed; workshops send a sample piece to our bench and meet a six-point checklist before they take a job; software firms get the specification and a sandbox, then pass conformance. Everyone on the network passed something to get there — that is what makes it worth being on.
Who owns my data and my customers?
You do, unambiguously. Your customers are yours, your books export on demand in open formats, and every store's data is isolated at the database layer with a full audit log. No hostage clause, no exit fee.
