How is a diamond certified?
A diamond is evaluated, measured, and scrutinized by trained individuals at the Gemological Institute of America (GIA) or the American Gem Society Laboratories (AGSL), using various industry tools. A certificate includes an analysis of the diamond’s clarity, color, dimensions, symmetry, polish and other characteristics. You should receive a certificate with any diamond you purchase. The GIA and AGSL laboratories are among the most respected in the diamond industry.
