GIA President William Boyajian explained GIA’s new cut grading system for round brilliant diamonds. The new system, which will be introduced next year, will combine brightness, fire, and scintillation, along with proportion factors, into a single cut grade. There will be five grades.

"Most of the diamonds coming through the GIA lab will fall into the first three grades," he said.

Boyajian added that the system will benefit the trade by encompassing a variety of international tastes and preferences while still requiring people to look at the diamond—"because there are a variety of different appearances among diamonds with the same cut grade."

How "above our heads" would this read be for non-industry semi-aficionados?

Where could we access it?

Four years ago Garry wrote for HCA:

Many diamonds with excellent scores may not be traditional 'ideal cuts' but we believe their value will rise once the GIA establishes its cut standard.

Now when AGS and GIA are about to release their new cut grading systems, prices of previously graded diamonds will be re-evaluated and we'll be able to fully appreciate Garry's efforts.
