The Gemological Institute of America will change the placement of “brillianteering” comments on its Diamond Grading Report and Diamond Dossier for round brilliant diamonds beginning on July 1, 2006.
Previously, when a diamond’s cut grade was influenced by “painting” or “digging out” the GIA placed a notation in the report’s comments section which read “Cut grade is based on the brillianteering of the half facets.” Beginning July 1 a similar diamond will have a statement notated under the proportions diagram, rather than the comments section, which reads “Cut grade affected by brillianteering.”
Brillianteering occurs after cross-working, when the star, upper and lower girdle facets are polished onto a diamond in its final stages of production. When a diamond is significantly “painted” or “dug out” it may influence the face-up appearance of the diamond.
GIA will provide a free re-issue service for three months to update any reports that have the original brillianteering comment.
