(Rapaport...July 1, 2006) The Gemological Institute of America (GIA) will update the wording and the placement of “brillianteering” comments on its Diamond Grading Report and Diamond Dossier® for standard round brilliant diamonds beginning July 1, 2006.
In a statement issued on June 30, the GIA announced it will also provide a free re-issue service that will be available for a three-month period, also beginning July 1. The service will apply only to reports that have the original brillianteering comment.
GIA’s new Diamond Grading Report and Diamond Dossier®, introduced nearly seven months ago, in January 2006, indicated when a diamond’s cut grade was affected by painting or digging out by putting a notation within the report’s comments section that read: Cut grade is based on brillianteering of the half-facets.
Starting July 1, a similar diamond will have a statement located under the proportion diagram –-not in the comments section-– that reads: Cut grade affected by brillianteering.
“We’re changing the language and location of the brillianteering comment on these reports so that all of the important information is included, while making sure that it is presented in a clear and understandable format to the consumer,” said Tom Moses, senior vice president, GIA Laboratory and Research.
Brillianteering refers to the last steps of the polishing process when the star facets along with the upper and lower half facets (also known as upper and lower girdle facets) are polished on the diamond. When a diamond is painted or dug out, these facets are polished in a manner that can affect the face-up appearance of the diamond and therefore may affect the final cut grade.
