Engineering a Rigorous Gemological Provenance Layer
Ceylon Gem Passport unites Swiss scientific clarity with contemporary Sri Lankan gemological heritage, establishing an auditable digital chain of custody.
Gemstone Registry
Immutable record generation (e.g. CGP-26-000001) with multi-point morphological data, high-precision carat metrics, and standardized color descriptors.
Multi-Tenant Tenancy & RLS
Complete PostgreSQL Row Level Security (RLS) guaranteeing strict tenant boundaries between mining syndicates, dealers, cutting ateliers, and laboratories.
Evidence & Document Vault
SHA-256 cryptographic checksums on private storage buckets, preventing unauthorized manipulation of pithead receipts, export permits, and rough scans.
Laboratory Report Verification
Structured references to accredited institutes (SSEF, Gübelin, GIA, Lotus) with explicit scope notes and issuer confirmation verification state.
Lineage & Transformation Graph
Directed acyclic graph tracking rough-to-cut transformations, split parcel events, recuts, and setting into jewelry without losing historical traceability.
Controlled Public Passport Snapshots
Public verification pages derived from immutable whitelisted snapshots — shielding private commercial invoices and proprietary seller information.
