The record starts in the pit.
Every stone begins in alluvial gravel. The first entry in its record is written where it was found, and every hand after that is added in order.
How verification worksBefore a stone is listed
Three checks. Thena signature.
Nothing here says “guaranteed”. It says checked, recorded, signed — words we can stand behind, with proof you can open.
Certificate, checked and signed by Jathi
The lab report is matched against the laboratory's own record — GRS, GIA, Gübelin, SSEF and others — then signed with Jathi's key. That signature is Jathi's own.
Licensed, identified dealers
Every seller holds a valid NGJA dealer licence, checked by Jathi, and completes an identity check before listing. The licence number sits on every listing in plain text.
A chain of custody, link by link
Every handover is recorded in order, each entry carrying the hash of the one before it. Editing any past entry breaks every link after it.
