First, know DeBeers and DTC, you know that diamonds are monopolized! 1. DeBeers De Beers It was officially incorporated in South Africa in March 1888. It is the authority of the world's diamonds and the largest and oldest diamond mining company in the world. DeBeers' business covers all aspects of the "Diamond Supply Line", from prospecting, mining, cutting, sanding, design and ultimately to the consumer. DeBeers had dominated more than 90% of the world's diamonds during its heyday, and now more than 60% of diamonds still come from DeBeers. 2. DTC Diamond Trading Company It is the world's largest supplier of rough diamonds for DeBeers' professional diamond distribution and promotion organization. In London, the most important role of DTC is to distribute rough diamonds, and its customers are called “seekersâ€. Only 93 sightholders from around the world travel to London and Johannesburg every year to participate in ten sightings a year. "DiamondisForever" is a global classic slogan from DTC, a professional distribution and promotion organization. Second, to understand the GIA of the American Gemological Institute, you know that it is the most authoritative of diamond valuation! In 1931, Robert M. Shipley founded the Gemological Institute of America (GIA) at Los Angeles in the United States. The first industry-recognized diamond grading standard 4C: color, clarity, cut and carat weight. GIA is a non-profit organization and the authority for international diamond grading. It is established by the well-known jewelers and celebrities in the United States. It is a research and evaluation institution shared by American jewelers. Its affiliated GTL provides identification services. GIA's achievements to date GIA has 14 teaching institutions around the world, providing professional research, sales, identification and other courses to cultivate high-quality jewelry practitioners, and also promoted GIA's reputation in the industry. The creation of the 4C standard unifies the global measurement of diamond quality. In 1939, De Beers took the lead in introducing the 4C standard into the evaluation of diamonds, allowing consumers to accurately understand the quality and characteristics of the diamonds they purchased. Third, the diamond itself is not divided into factories and brands, the value of GIA certified diamonds is clear! Due to the “monopoly†of diamond DeBeers, the diamond itself is not part of the factory, and the so-called brand is just a cloud, for the diamond itself is just a waste paper wrapped in diamonds, no value! Only diamonds that have been evaluated by the strict 4C standard know their true value, and GIA is undoubtedly the most authoritative in the world, and the value of GIA-certified diamonds is clear.
