STANDARDIZED WORKFLOW

The 9-Step IGL Laboratory Chain of Testing

Designed for complete scientific accuracy, traceability, and document security.

Specimen is physically presented at the IGL laboratory intake counter by client or authorized courier with intake documentation.

Specimen undergoes high-security intake, digital photography, micro-weighing, and assignment of an anonymous barcode tracking identifier.

Initial optical measurement including Refractive Index (RI), specific gravity hydrostatic check, and polariscopic optic figure observation.

Advanced diagnostic testing utilizing binocular darkfield microscopy, UV-Vis spectroscopy, and luminescence screening.

Double-blind review by senior gemological analysts to record consensus findings on species, variety, and treatment indications.

Data is compiled into the IGL secure reporting system, generating cryptographic QR verification hashes and serial numbers.

Final quality assurance check verifying document parameters, physical specimen match, and seal application.

Physical IGL security report is printed with micro-line anti-copy security and packaged alongside the returned specimen.

Report data is indexed to the public verification registry on AmericanGemology.com for 24/7 global QR authentication.
