Understanding Your IGI Diamond Report
Key verification steps and documentation standards for professional diamond buyers.
1. Report Number & Verification
Each IGI report has a unique report number. Buyers can use IGI's official report verification service to check the report details.
2. Diamond Identification
Review the diamond's stated shape, measurements, carat weight, color, clarity, and other information documented in the applicable report.
3. Laser Inscription
Where applicable, the girdle inscription can help buyers compare the inscription with the report details. An inscription alone does not prove that a stone matches a report.
4. Match the Report to the Stone
Before purchasing, verify the individual diamond and its documentation. Availability of report details and inscriptions may vary by stone and report type.

Know What Your IGI Report Tells You
An International Gemological Institute (IGI) report provides third-party verification of a lab-grown diamond's 4Cs, optical characteristics, physical measurements, and growth methodology. Each report applies exclusively to the individual stone described.
Unique Report Number & QR Code
Every certified stone receives an individual report number and digital QR code that links directly to IGI's secure online database, ensuring transparent traceability for professional buyers and end clients.
Girdle Laser Inscription
The matching IGI report number and “LABGROWN” notation are microscopically laser-inscribed on the diamond's girdle, allowing rapid physical verification under 10x gemological magnification.
Comprehensive 4Cs Evaluation
Independent gemologists evaluate exact carat weight to two decimal points, calibrated color grade, clarity classification, and overall cut performance against international laboratory benchmarks.
Exact Proportions & Dimensions
The report details millimeter measurements (length, width, depth), table percentage, depth percentage, girdle thickness, and culet size, enabling jewelry manufacturers to engineer precise CAD mountings.
Growth Method Confirmation
The report clearly indicates whether the diamond was produced via Chemical Vapor Deposition (CVD) or High Pressure High Temperature (HPHT), confirming ethical, laboratory-grown origin.

Grading details apply strictly to the specific diamond evaluated. Buyers can inspect digital copies of reports prior to shipment to verify complete alignment with their commercial requirements.
