Gem and Diamond Certification Process
Accurate, Transparent, and Trusted Testing Methods
Submission
You submit your gemstone or diamond, either loose or mounted, to our laboratory for testing and certification.
Preliminary Inspection
Our gemologists perform an initial visual examination to record the stone’s appearance, size, and basic characteristics.
Advanced Testing
We use GII-approved advanced equipment to identify the stone, verify its authenticity, detect any treatments, and, where possible, determine its origin.
Grading and Analysis
Diamonds are graded according to the 4Cs — Cut, Color, Clarity, and Carat Weight — while gemstones are assessed for species, variety, and quality.
Report Preparation
We create a detailed certification report, complete with verified details, grading results, and high-quality photographs for identification.
