The GIA Diamond Grading Report and GIA Diamond Processing are considered to be the world's number one gemstone certificate, known for its fairness. The Academy's groundbreaking research and its own education, experimentation and equipment development process are almost a chronicle of the growth of the jewelry industry.

The Antwerp Certification Laboratory (HRD Antwerp) was founded in 1976 by the Antwerp World Diamond Center and is part of the Belgian government. As the diamond identification certificate issued is a symbol of quality and authority, the Antwerp certification laboratory HRD Antwerp is recognized and respected by the international community. The HRD Antwerp Diamond Certificate is fully compliant with the polished diamond scoring rules established by the International Diamond Center (IDC) and is also recognized by the industry's representative bodies, the World Diamond Federation (WFDB) and the International Diamond Manufacturers Association (IDMA).

Some diamonds on jewels might not have a certificate, this due to lower the cost of certification.
