Diamonds are dazzling and expensive. Because of this, many merchants shoddy and confuse the real with the fake, which makes it impossible for consumers to tell whether the diamonds they bought are real or not. In order to solve these problems, relevant institutions have formulated the most authoritative standard diamond certificate to identify diamonds. The following small series introduces four common authoritative diamond certificates: GIA certificate, IGI certificate, HRD certificate and AGS certificate. As long as we buy any kind of diamonds, we don't have to worry about quality.

Analysis of four kinds of common authoritative diamond certificates;

1.GIA diamond certificate

GIA diamond certificate is the most widely used and well-known diamond certificate. GIA, the abbreviation of GemologicalInstituteofAmerica, has a history of more than 70 years and is trusted by the whole world in diamond grading and gem identification. As we all know, the first diamond grading system in the world was formulated by GIA, the most authoritative diamond appraisal institution in the world.

2.IGI diamond certificate

IGI certificate is issued by the international gemological society, which was established in 1975. It is the oldest gemological research institute in the world and the largest independent jewelry appraisal laboratory in the world. There are 15 laboratories in the global diamond trading center, which is known as the authoritative appraisal institution around consumers, and the authority of its IGI certificate has also been recognized all over the world. In addition, consumers are reminded to choose IGI diamond certificate when buying eight-heart and eight-arrow diamonds, because only IGI can issue eight-heart and eight-arrow diamond certificates at present, which is respected by the world.

3.HRD diamond certificate

HRD certificate, issued by the Belgian Diamond High Conference (HogeRaadVoorDiamant), is the most comprehensive and safest diamond certificate at present. HRD diamond certificate describes the 4C grade of diamond in detail. If you need to know the details of diamonds, you can buy diamonds with HRD diamond certificate. In Europe, HRD diamond certificate is far more popular than GIA diamond certificate.

4.AGS diamond certificate

AGS diamond certificate is issued by American Diamond Association. The characteristic of AGS certificate is the most important cutting in 4C cutting of diamonds. For example, a diamond with a cut level of 0 is the ultimate performance of diamond cutting. If there are three zeros, it means that the proportion, polishing and symmetry of diamonds are the most perfect.
