Every certificate, read once and attached forever.
CaratList is the jewellery data layer under MergeKart. Lab reports, hallmarks and 4C grades become first-class attributes on the SKU — listable, filterable, and impossible to contradict.

The certificate is the asset. Most tools treat it as a PDF attachment.
Data locked in a document
A lab report holds the only authoritative grades you have, and no field on your listing points at it.
Hallmarks read by eye
Metal purity is stamped on the piece. Typing it from a photo at 2am is how 585 becomes 925.
No way to filter your own stock
“Show me every 1ct+ VS or better in yellow gold” should be a query, not an afternoon.

It is built for the lab certificates fine-jewellery sellers work with day to day. Confirm your specific labs in a demo rather than assuming coverage.
No. An unreadable value is shown as a gap for you to resolve. A wrong grade on a graded stone is worse than a missing one.
CaratList reads the certificate; Magic Lister builds the draft around it and PixelMagic handles the imagery. They are designed to be used together.
It is built for fine jewellery generally — the certificate-to-listing path applies wherever graded specifications drive the listing.
Send us five certificates.
We will enrich them live and show you the catalogue query afterwards.
