A Diamond’s Best Kept Secret: The Fifth 'C' - Certification
How can I be confident with my diamond purchase?
The only way to be absolutely sure of the quality of your diamond is to have it certified. A certification is an independent, objective quality report issued by an outside laboratory and includes the exact measurements and proportions of your diamond as well as the color, clarity and carat weight. Each certification has its own number, the date which it was analyzed and a plotting of the diamond which shows the inclusions in the diamond. The two leading labs in the world that offer these unbiased certifications are: GIA- Gemological Institute of America and EGL USA- European Gemological Laboratory.
What is the difference between an appraisal and a certification?
There are no official guidelines to issue an appraisal. An appraisal is the opinion of a jeweler affiliated with the store selling the diamond. A certification is an independent, objective opinion of a diamond issued by a laboratory. It is the most important consideration when purchasing a diamond. The certification is the only way to be absolutely positive about the quality of your diamond.
