Carlsbad, Calif., − Jan. 22,  2008 − Al Gilbertson, a noted Gemological Institute of America (GIA) Research Associate, recently published his first book, American Cut: the First 100 Years that deconstructs modern understandings of the historyof the American “Ideal Cut Diamond.”
The book is published by GIA and is now available to the general public by simply calling (800) 421-8161 or visiting www.gia.edu and clicking on "Instruments and Books."

American Cut follows the history and character of American diamond cutting. It describes the early stages of the European diamond cutting industry, and how American ideas and inventions influenced diamond cutting eventually changing diamond cutting around the world.

Donna Baker, president of GIA said, "This important work will change your understanding of how and why diamonds are cut the way they are today. It’s a compelling story of American ingenuity and the drive to make diamonds sparkle with life. American Cut: The First 100 Years sheds light on a piece of history that is important to anyone who is fascinated by diamonds.”

Gilbertson, a Graduate Gemologist and former appraiser and lapidary helped create and refine GIA’s Diamond Cut Grading System. He has closely studied the history of "ideal cut" diamonds since 1976 and has compiled that information into a story he thinks the jewelry world should hear.

"Throughout the years, we've built this mythology about diamonds, about what we think happened and when, and we've condensed it into neat little packages," Gilbertson says. "But the actual history is far more complex than that, and I think it's important to provide context, even correction, to a heritage so very rich. There are lessons to be learned from it."

Gilbertson has enjoyed a notable career in the gem and jewelry industry for more than 30 years. He began cutting gemstones as a young boy in his father’s lapidary business in Tehachapi, California. He was later employed as a custom gem cutter for a fine jewelry store, where he completed the GIA courses to become a Graduate Gemologist.

Gilbertson went on to earn the title of Certified Gemologist Appraiser from the American Gem Society, and was one of the first Independent Certified Gemologist Appraisers in the country, operating a highly respected jewelry appraisal firm that provided services to more than 50 jewelry stores in the Pacific Northwest. He is a noted speaker for national jewelry and appraisal associations and the published author of numerous articles related to the jewelry and appraisal business.
