For jewelers · gemologists · pawn shops
Appraisals your clients can verify.
Metal quotes, a gem calculator and professional reports with sequential numbering and a public verification page. For jewelers who want to hand over trust with every piece.
Tools
Five instruments.
One craft.
Not an ERP. It's the jeweler's digital workbench: instant quotes, documented appraisals and a direct channel of trust with the client.
Metal calculator
Gold 24K · 18K · 14K, silver, platinum and palladium with an up-to-date quote. No sign-up.
Open →Gem calculator
Indicative valuation by type, quality, treatment and weight. Over 100 stone and diamond types.
See demo →Appraisal reports
PDF with sequential number, jeweler details, breakdown by stone and setting. Ready to hand over.
See example →Public verification
Every report gets a unique URL and a QR. The client checks authenticity and validity, nothing to install.
How it works →Warranty certificates
Your establishment’s warranty certificates —not quality ones— to hand over with every piece sold: they identify the jewel and its characteristics, with no value data, with a verification QR. And if you resell second-hand online, it’s the kind of document platforms recommend to prove authenticity.
See the method →Trust, not marketing
Every report comes with its own verification page.
When a report is finalized, a unique link and a QR code are generated. From any device, the client confirms that the document in hand was issued by their jeweler and whether it is still valid.
And if the piece ever disappears, that document — with its photos, characteristics and date — is the proof it existed that the insurer will ask your client for.

Warranty certificates
Add something to every sale that your competition doesn't hand over.
A certificate from your establishment that identifies the piece with the correct terminology —origin, treatments, quality— and goes out with your name and your logo. It declares no monetary value: it is not an appraisal or a laboratory certificate.
Your brand
Your name and logo on the document
No value data
It identifies the piece, does not appraise it

QR and public page, nothing to install
After a theft
Useful for the police report and the claim
CIBJO, the world jewellery confederation, recommends in its Blue Book accompanying the sale of jewelry and gems —including online— with its warranty certificate.
An appraisal is only worth what the client can verify. That is why every report is born with its verification.
