GIA Certified Diamonds

A report from GIA is an expert statement of a gem’s identity and quality characteristics. A GIA report is not an appraisal of financial value, but your assurance of your gemstone’s quality. It has a clear disclosure if the material is synthetic or if it has been treated to enhance or alter its appearance. The report provides evidence that is vital to a confident gem or jewellery purchase.

As a non-profit, public-benefit research and educational institution, GIA is an independent and impartial entity for evaluating the quality of gems and delivering unbiased information on them. GIA does not sell gemstones, nor does it represent the interests of gem sellers. Globally, GIA is relied on when it comes to identifying and evaluating gem materials.
