Stone Passport
Every verified stone on Mahad Gems carries a Stone Passport — a tamper-evident digital record of what it is, where it came from, how it was treated, and the media that proves it.
Media is the trust system
Every lot on Mahad Gems carries a media bundle — macro for inclusions, daylight video for true colour, scale for size, certificate for treatment, QC for export readiness.
