GIA announces official cut grade to launch Jan 2006.

The GIA announced this at a press conference Monday evening. The grading system for round brilliant cut diamonds is scheduled to launch Jan. 1, 2006.

"We're ready to go today," said GIA president William E. Boyajian at a press conference in New York Monday afternoon announcing the timetable. Boyajian told attendees that GIA wanted to be sure the industry was ready.
"We don't want to launch something the trade isn't prepared for," he said. "It's obviously a big deal."

The new reports will impact all round brilliant cuts. Cut grade will accompany the three other Cs: color, clarity, and carat weight on the new reports. The new grade will also be included on GIA's Diamond Dossiers. The grade will take into account brightness, fire, scintillation, design, and craftsmanship. The system is based on a predictive modeling of more than 38.5 million proportion sets, which has been validated through human observation.

Since January of this year, the labs have been collecting proportion information on most of the round brilliant diamonds graded, Boyajian said. A free reissue service will be offered on diamonds graded from now until the end of the year, while there will be a nominal fee to reissue reports on diamonds graded between Jan. 1-July 31 of this year.

During the implementation period, the industry will be given access to software and support tools. They will be able to estimate GIA cut grade using a free online version of the trademarked GIA Facetware Cut Estimator, accessible via DiamondCutGIA.edu. Additionally, Sarin and OGI have introduced new software in their optical measuring devices that has embedded the new GIA system, enabling users to estimate cut grades and gain advice on polishing from rough and recutting.

To further support the implementation, GIA has also released: a standardized viewing environment, the trademarked GIA DiamondDock, which provides optimal lighting for both assessing and displaying the cut quality of round brilliant cut diamonds; the GIA Multi-Purpose Gemological Reticle, which provides a way to measure the proportions of a diamond manually with a microscope; and a new brochure for the industry that explains the new system and how it will be presented on GIA lab reports.

The GIA cut grade will not be proprietary, Boyajian added.

"We hope the industry as a whole will adopt the system," he said. While there is no timetable yet, he said cut grades for round modified diamonds and fancy shapes will be developed.

"If I have any influence, it will be on stones that are the more popular fancy shapes," he said.

GIA's history is rich with research and discovery. In the 1950's, GIA created the International Diamond Grading System, and established the standards that revolutionized the diamond industry.

When I think back to that era of innovation, it is truly awe-inspiring. A lot has changed since then. But GIA's passion, integrity, and commitment to research remain the same.

I'm pleased to introduce the new GIA Diamond Cut Grading System. With advances in computer modeling, we have been able to unlock the mystery of diamond cut ? arguably the most complex and contested of the 4Cs. After more than 15 years of research and discovery, GIA has developed a scientific way to assess ? and predict ? the cut quality in round brilliant cut diamonds.

The most exciting and reassuring conclusion of our research is that there is no single set of proportions that define a well-cut round brilliant diamond. Our research has shown that many different proportions can produce attractive diamonds.

GIA has also developed software that provides a method of estimating a cut grade ? and a database that is embedded into a number of leading diamond measuring devices so that this estimation can be automated. As a result, manufacturers can plan and, in effect, predict cut grades, buyers can compare cut qualities, and retailers can communicate the effects of cut on round brilliant diamonds.

GIA's mission of ensuring the public trust in gems and jewelry is reflected in this international research undertaking. And reminiscent of GIA's early innovations, I believe we will set the standards for cut quality the way we have set them for color and clarity for more than 50 years.

Sincerely,

William E. Boyajian
President
