GIA is a non-profit organization, and its funds are donated by people in the jewelry industry. Its main service scope is jewelry appraisal and professional knowledge education and research, which is deeply recognized by the global jewelry industry. GIA is the founder of promoting the internationalization of diamond certification.
It also provides authentication certificates for many consumer brands facing the public. For example, the famous American online shop "Blue Nile" focuses on mainstream middle-class men, and basically uses GIA and AGS certificates. ?
When Tiffany took the middle-class route, she used a lot of certificates from American Gemological Institute. With the deviation of self-positioning and brand marketing from GIA mass positioning, I began to use my own certificate. ?
GIA certificate emphasizes unity. There is a sense of standardization like an assembly line. From the page of the certificate, the star's jewelry and the goods in the street shop all use the same plate making and design.
