There are three most authoritative diamond institutions in the world, namely IGI, GIA, HRD IGI: Igi (Institute) of the International Gem Institute, which was established in the World Diamond Center in 1975. The largest independent jewelry appraisal laboratory has a total of 12 laboratories in major diamond trading consumption centers in the world, known as "authoritative appraisal house around consumers". I. As the only realist laboratory of the three authoritative institutions, IGI has excellently completed the highly unified challenge of the standards of each laboratory. Its high stability has been widely respected by the industry. International brands such as Cartier and many famous domestic brands choose IGI to provide identification or training services. igi certificate is well worked well, the information provided is meticulous and intuitive, and the laser characters on the diamond waist are taken as a photo and printed on the certificate. Recognize and check the purchased diamonds.
gia: This GIA (Institute of American) was established in Los Angeles in 1931, and the concept of diamond 4C grading system was proposed in 1953. Later, under the common improvement and promotion of the three major institutions, the system gradually developed into a diamond grading system we are familiar with today. gia's diamond laboratory has one in California and Los Angeles, and there are color gemstones in Thailand; its current president is Donna Baker, the only female president in GIA history. Because GIA entered the Chinese market earlier, consumers have closed the awareness of other international authorities, so the previous consumers only knew this choice. GIA's funding is mainly donated by industry people such as jewelry merchants. Although its nature is non -profit institution, its appraisal charges are also the highest of the three major institutions. Consumers must pay more certificates for the purchase of GIA diamonds they purchased. Essence gia certificates list the detailed information and data of diamonds, but it is more difficult for consumers to identify the purchased diamonds based on the information on the certificate.
HRD: This HRD (Hoge Raad Voor Diamant) was established in Antwerp in 1973. Its duties at the time were as an industry institution to promote Antwerp's diamond center status. In 1976, one year later than IGI. Due to the conflict with the functions of the industry association with a profitable nature of the profitability, the original HRD reorganization was established after the HRD reorganization. Performing the certificate business of HRD, this is the HRD we know today. The certificate information is not as detailed as the previous two, and the workmanship is relatively good. The HRD diamond appraisal report is mainly used in Europe.
Foreign abroad is usually English. It is recommended to look at the domestic appraisal institute. Because foreign testing is different from domestic, in addition, the language poor is often used by adulterers
