Certificates of authenticity, created in seconds

Sell a piece and the certificate is already written. The product, the photo, the metals, the gems, the customer and the currency all come off the order. You choose a design, confirm the appraised value, and print it or send the QR.

How it works

Three steps, and two of them are just confirming.

Nothing about a certificate needs to be typed twice. The order knows what was sold, the product knows what it is made of, and the contact record knows who bought it.

1Sell a piece

Start a certificate from an order, or from a single line on it. The product, its photo, the title, the price, the currency and the customer come across with it.

One order with several pieces can also take a single global certificate, with its own title, total weight and amount.
2It is already itemised

Every metal with its weight and unit, every gem with carat, shape, colour, clarity and quantity. You are reading it, not writing it.

Metal the customer supplied from their own deposit is listed as theirs, not yours.
3Print it or scan it

A print ready PDF, straight to a configured printer. Or a blanco version with no background, for the pre printed paper you already buy.

Either way it carries a QR to a portal where the customer can verify it and download it again.
What it carries

A component list, not a description.

A certificate that says "diamond ring, 18K" is worth very little to a valuer in fifteen years. Gem Logic builds the certificate out of the piece's actual components, the same ones you entered when it came in.

Client metal is marked as theirs

When a piece is partly made from gold the customer brought in, the certificate says so and names the deposit it came from. It matters for provenance, and it is the honest answer to what the piece is worth. Same record the creation carried.

One ID, fourteen digits, permanent

Every certificate gets its own reference, its own date, its own language and its own currency. Sell to a French customer in euros and to an American in dollars, from the same shop, on the same afternoon.

Edit, then regenerate

A weight was wrong, a title needs rewording. Change it on the certificate and produce the PDF again. The list of every certificate you have issued is searchable, filterable, and takes bulk actions.

Designs

It should look like it came from your shop, not from software.

Several designs, portrait and landscape, each with its own background artwork. Preview the one you pick with sample data before you commit, then put your logo, your address and your signature on it.

Then make it yours

Logo, background image, company name, address and contact details. Draw your signature on screen or upload one. Add your own certificate terms. Decide what the customer should not see: the value, the weight, the photo, their own details.

Verification

The paper is at home, in a drawer, possibly lost.

The moment a certificate is needed is rarely a moment anyone can find it. Every certificate carries a QR to a public portal, so the customer can pull it up on a phone, check it against the ID, and download the PDF again.

By scan, or by typing the ID

The QR is the fast path. The fourteen digit reference is the one that still works when the QR has been through a washing machine, or when someone is reading it down the phone to you.

The portal wears your logo too

A customer scanning a code on your certificate should not land on a page branded by your software vendor. The portal takes its own logo.

And you can find it too

Every certificate you have ever issued stays on the piece and on the customer's record. When someone calls about a ring bought in 2019, you are not searching a folder of PDFs by filename.

Could you reissue a certificate you wrote three years ago?

If it was a Word file, the answer depends on whose laptop it was. Book a demo and we will issue one from a piece in front of you.
