Each and every diamond is unique and has parameters that are both subjective (color, clarity, polish, etc.) and objective (carat weight, dimensions, etc.). A gemological grading laboratory or institute analyzes and evaluates all the characteristics of a diamond using various tests and equipment. After verifying all the information, a report is created unique to that particular diamond. This document is commonly referred to as a dossier, certificate or report.
We strive to provide the most accurate information for each of our diamonds. Every diamond of 0.30 carats and larger is independently graded by one of the major gemological laboratories - European Gemological Laboratory (EGL USA), Gemological Institute of America (GIA) and International Gemological Institute (IGI). Currently American Gem Society (AGS) does not grade synthetic diamonds.
By default, we render services of EGL USA to grade our diamonds. On a customer's request, we can provide a grading report done by GIA, IGI or any other major gemological laboratory that grades lab-grown diamonds.
Below you can see a sample certificate for a 1.10ct round yellow diamond from both EGL and GIA to see the detail and differences:
We provide all the relevant details and measurements for each of our certified diamonds online. All details can be verified through EGL's online results. GIA does have an online lookup, but this service does not include synthetic diamonds. Contact us and we can email you a scan of any report.
