Both institutions are very authoritative . The difference is 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 American Institute of American. GIA was the promotion of diamond identification 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.
If you are a diamond practitioner, you will understand that the GIA certificate is divided into "big certificates" and "small certificates". In order to prevent counterfeiting, there is generally GIA laser code. This code is the number of the certificate, which is common in diamonds above 25 points and less than 1 carat. The so -called "big certificate" is that the certificate looks relatively large, and the content of the certificate is extremely detailed, including the two diamond defective details (clarity diagrams). Because the flaws of each diamond are unique, just like the fingerprint of human beings, sometimes there is no GIA laser code on the certificate, which is common in> 1 carat diamond (usually $ 100) diamond. In addition to the appraisal fee, all GIA appraisal departments are located in the United States, and transportation costs and waiting dates are also incredible.

As the world's largest jewelry appraisal agency, IGI has almost covered the world from New York, Bangkok, Mumbai, Tokyo, to Dubai, Traviv, etc. It is a statement that it provides the authenticity of diamonds with the recognized system of the world and provides reliable and correct diamond identity and level, so it is more recognized by consumers.
