After the decision to purchase the diamond has been made, the customer must next ask for a copy of the certificate, which guarantees that the stone has undergone an unbiased, professional examination
What is a Certificate?
A diamond certificate (also known as diamond grading report, diamond dossier or diamond quality document) is a report prepared by a team of gemologists. They evaluate, measure and study the stone with trained eyes, a jeweller's loupe, a microscope, and other industry tools. The final certificate includes an analysis of the diamond's dimensions, clarity, color, polish and symmetry among other things. Most round diamonds also include a cut grade in the final certificate.
IGI's Grading Standards
Worldwide, consumers depend on the International Gemological Institute or (IGI) reports as the final word on the quality of the precious stone. The IGI is famous for its strict impartiality and adherence to the international grading standards. All IGI Laboratories worldwide follow a set of basic principles, which protect the objectivity and accuracy of every report released. The IGI Laboratories are characterized by highly trained staff, state-of-the-art security and monitoring features.
GIA Certification
The Gemological Institute of America or GIA as it is famously known is a non-profit organization conducting research and studies in the field of jewellery and gemology. Since 1931, the GIA has been studying and maintaining the standards used in understanding the quality of gems and other precious metals. The institute is a world-famous data bank on different topics related to gems and jewellery and offers consultations to people in the business, the general public and the media. The Four Cs (cut, clarity, color, and carat weight), used as an international standard to understand the quality of diamonds, was brought out by the GIA in 1953.
