The national inspection is a certificate we made for the finished product (that is, the bare diamonds inlaid on the precepts). This test that needs to be done with the finished product. In addition to testing the diamond, it also checks the material of the ring and the weight of the ring. Such as diamond material, diamond color diamond clarity, etc.
The diamonds showing the certificate of the certificate. Each diamond waist is marked with GIA numbers. This encoding is the same as the code on the certificate, which is also the only one in the world. The GIA certificate is evidence of diamond grading identification. It is currently the world's most authoritative diamond appraisal certificate. The national inspection is an authoritative certificate in China, and its diamonds are not as detailed as GIA certificates. Big names like Levez will be inlaid with bare diamonds with GIA certificates above 30 points. It is also required that each man's customization needs a real -name system, which means "life and one life will not be abandoned". Intersection
GIA is the abbreviation of American Gem Academy, and the full name is Institute ofamerica.
GIA was founded in 1931. It has a history of 80 years. It is the earliest authoritative appraisal agency in the world to establish an international diamond 4C standard. The 4C standard is rated for classification. Therefore, diamonds with GIA appraisal certificates are deeply trusted and respected by consumers in world diamond trading. They are currently the most authoritative diamond appraisal agency in the world.
GIA has the world's recognized authority. Both the White House and Congress have helped GIA backlook, defined as non -profit business institutions and the world's largest gem and jewelry library. GIA set up a benign transaction guarantee between the diamond industry and consumers. Of course, the main reason is that GIA always stood in objective rationality and never stopped studying and continuously cultivating talents.
