Paperback with 2 posters in slipcase . Edited by James Shigley, published by the Gemology Institute of America, GIA. From an online description:

"Once limited to easily detected dyes and coatings, diamond treatments pose formidable challenges for today s jewelers and gemologists. Gems & Gemology, GIA s award-winning quarterly journal, has combined 70 years of its coverage in a new volume titled Gems & Gemology in Review: Treated Diamonds. This book marks the third installment in G&G s review series, following Synthetic Diamonds (2005) and Colored Diamonds (2006). Edited by GIA distinguished research fellow Dr. James E. Shigley, Treated Diamonds covers the range of enhancement techniques that have been performed to improve color (coating, irradiation, and high-pressure/high-temperature annealing) and clarity (laser drilling and fracture filling).

Each of these sections is preceded by an informative overview of the treatment process. The book features more than 300 richly illustrated pages and includes a chart on identifying fracture-filled diamond."
