GIA is the world’s most trusted name in diamond grading and gem identification. With objectivity and expertise as its hallmarks, GIA ensures the integrity and accuracy of every report it issues. GIA tests every material submitted to determine whether it is natural or not, and discloses any treatments discovered during our examination.
Houses have deeds. Vehicles have titles and registrations. It only makes sense that you have similar documentation for something as precious as a gem purchase.
A report from GIA is an expert statement of a gem’s identity and quality characteristics. A GIA report isn’t an appraisal of financial value; it’s is your assurance of your gemstone’s quality, with clear disclosure if the material is synthetic or if it has been treated to enhance or alter its appearance. The report provides the kind of evidence that is vital to a confident gem or jewellery purchase.
