Diamonds in the news: Diamond cut grades topic of Centurion breakfast
Excerpt:
The Gemological Institute of America introduced some of its key findings on cut grade research at a breakfast seminar during the recent Centurion jewelry show held Feb. 1-5 at the Westin La Paloma Resort in Tucson, Ariz. GIA intends to incorporate expanded cut information on all its grading reports and Diamond Dossiers for all standard round D to Z color diamonds, possibly as early as later this year.
In a move certain to arouse controversy, GIA has definitively stated that a range of proportions can produce a top cut grade, rather than having only one single set of proportions be considered the benchmark.
