Most of the material presented here was originally published in Gems & Gemology as articles and lab notes (short reports from the GIA Laboratory, formerly called the Gem Trade Laboratory) or as Gem News/Gem News International items between the years 1938 and 2007. Also included are summaries of presentations at GIA's 2006 International Gemological Symposium and Gemological Research Conference, which originally appeared in the Fall 2006 Proceedings volume produced by Gems & Gemology staff. The present work is organized in two main parts on color treatments and clarity treatments, with color photos and microimages on almost every page. Chapters in the section on color treatments cover coated diamonds, irradiated diamonds, and annealed diamonds. Chapters in the section on clarity treatments cover laser-drilled and glass-filled diamonds. Material is presented in chronological order to help readers follow the evolving areas of interest and understanding of these treatments. Some of the older material includes editorial comments to explain now-unfamiliar concepts or discuss significant development since the original publication. The book includes a poster-sized color chart enclosed in a side pocket, with color photos demonstrating diagnostic features of filled diamonds and testing techniques. Shigley is a distinguished research fellow at the GIA Lab in Carlsbad, California.
