How It Works

From mine to
digital identity.

I
Mining Origin

Stone is documented at the source — Panjshir Valley and other ethical mining sites — with GPS, date, and photographic evidence.

II
Gemological Analysis

Professional gemologists assess colour, clarity, cut, weight, and inclusions. AI identification provides an independent verification score.

III
Digital Passport

A unique Digital Gem Passport is issued with QR code, blockchain anchor, 3D model, and complete provenance documentation.

IV
Transfer of Ownership

Every change of ownership is recorded on the blockchain. The passport travels with the stone — permanently and immutably.
