The American Gem Society's Diamond Cut Grade System
and its Supporting Technology

Speaker: Patrick B. Stout
Education Services Manager at the American Gem Society

Before joining the AGS in August 2005, Patrick spent nearly twenty-five years in the retail sector in various sales and management positions with firms such as Ben Bridge Jeweler and Tiffany & Co. He has been a member of the American Gem Society since 1988, becoming a Certified Gemologist in 1989 and a Certified Gemologist Appraiser in 1998. He also is a GIA Graduate Gemologist.

The American Gem Society Diamond Cut Grade System is supported by the "Angular Spectrum Evaluation Tools", better known simply as "The ASET Tools". These tools allow you to demonstrate, in vivid color, how efficiently a diamond is using light. It's accurate. It's easy. It's fast. It's fun. These tools help you to take the guesswork out of the subject of diamond cutting for your clients and allow you to demonstrate and describe "Cut" in a way that clients can easily comprehend, without boring them to death with overly technical explanations. At the same time, the nature of this cutting-edge technology will greatly appeal to your more "techie" clients. Five patents have been awarded covering this system from research to reality.

In this presentation, you will learn about this revolutionary system and the tools that can explain light performance in red, blue, and green. Come learn and discuss the advantages of using this technology in your diamond sales presentations.

B.Y.O.D! Bring Your Own Diamond! Bring along a diamond or two out of your own inventory and see how it performs in the ASET tools.

The above link provides an excellent explanation on the parameters for the new Diamond Cut Grade.

The new Diamond Lab Manual is also extremely helpful in understanding the concepts of the system. This manual can be purchased through the GIA for $50.00. There are a couple of mistakes in the new manual that the GIA will not have the opportunity to correct with this printing. They are:

Page 62: Chart for Girdle Thickness % no longer has a grade for anything below 2.5.

Page 61: Diamond Cut Grades & Pavilion Angles:
EX,VG, G, F, P: 40.6° to 41.8°
VG,G,F,P: 39.8° to 40.4°

Page 54 & 55: Painting & Digging Out:
Poor has been eliminated.

The Alumni Society is evolving!
