A gemstone certificate is an official document issued by a recognized gemological laboratory (e.g., GIA, IGI, AGS, or GRS) that authenticates and details a gemstone’s characteristics. The certificate typically includes: Type of gemstone Weight (carats) Cut and shape Color and clarity Treatments (if any) Origin (sometimes included)
Type A jade refers to natural, untreated jadeite jade that has not undergone any artificial treatments such as bleaching, polymer impregnation, or dyeing. It is considered the most valuable and authentic form of jade, especially in Chinese culture.
GIA does not “certify” diamonds but rather grades them and issues a report. However, the term “GIA Certified Diamond” is commonly used to refer to diamonds that have been graded by GIA for their cut, color, clarity, and carat weight. GIA-graded diamonds are trusted worldwide for their accuracy and reliability.
The GIA Report Check is an online tool that allows buyers and sellers to verify a diamond’s GIA certification using the report number found on the certificate. This ensures the diamond's details match the official GIA database. The tool can be accessed on GIA’s website.
A GIA diamond refers to a diamond that has been graded and certified by the Gemological Institute of America (GIA). GIA does not sell diamonds; instead, it provides an independent and highly respected assessment of their quality.
