GIA Unveils "New" Cut Grade

Finally, a GIA cut grade for round diamonds. After years of study, computerized modeling techniques and debate, the GIA has announced its new five-grade system for proportion analysis. A lot of science went into this system that looks at angles, percentages and light return so while the chosen nomenclature isn’t too exciting, it is easy to present. It goes Excellent, Very Good, Good, Fair and Poor. Their new Facetware™ software can be picked-up on-line to do your own estimates and the Gem Trade Lab will start using the system in 2006. This will not result in any changes at NGL, since these are the terms we have always used!
