Diamond Certifications

When you're buying expensive jewelry, you should request a lab report from a reputable gem lab. A lab report can provide you with detailed information about a gemstone's color, clarity, proportions, and treatment status.

Some reputable gem labs are the Gemological Institute of America (GIA), AGS Laboratories (AGSL), Gem Certification & Assurance Lab (GCAL), International Gemological Institute (IGI), and the European Gemological Laboratory (EGL).
