The Diamond GIA certificate was founded by the Jade College of the United States; IGI is the authority of the World Diamond Center Belgium International Gem Institute. The difference lies in the clarity standard. The highest GIA is FL, and then if; IGI is the highest if, and the others are the same. IGI Certificate: Igi (IGI () Antwerp, which was established in the World Diamond Center in 1975. It is currently the world's largest independent jewelry appraisal laboratory. Antwerp, New York, Toronto, Dubai, Tokyo, Hong Kong, Traviv, Los Angeles, Mumbai) has a total of 15 laboratories, known as "authoritative appraisal house around consumers".
GIA Certificate: 1931 Mr. Robert M.Shipley founded the Institute of America. GIA was the promotion of diamond appraisal certificates into the founder of internationalization. GIA is a non -profit institution. The funding industry is donated by people in the jewelry industry. The main service scope lies in the education and research of jewelry appraisal and professional knowledge, which is well recognized by the global jewelry industry. So far, GIA has 14 teaching institutions worldwide, providing professional research, sales, appraisal and other courses, cultivating high -quality jewelry practitioners, and also promoting GIA to have this lofty reputation in the industry, so that the public's trust and the degree of trust and the degree of trust in it Professional has always maintained the status of leading the world. Now the 4C standard proposed by GIA is also a common standard for the international jewelry industry. GIA official website query: http://www.gia.e //
GIA is universal. Every diamond is given a certificate. IGI generally identifies the better quality diamond. Essence This is what people in the jewelry shop said to me
GIA is authoritative. The level of the same diamond will be higher than GIA, and the diamond level from IGI will be dropped by GIA. International and domestic first -line brands will be equipped with GIA certificates. Some 5 and 6 brands will be equipped with IGI certificates, and the certificate level is unstable. Now the IGI certificate share is very small, everyone recognizes GIA, HRD, and national inspection.

GIA's authority is higher than IGI
does not rule out special circumstances. After all, is it also identified by people?
