We publish courtesy of GIA’s Gems & Gemology GIA Insider

Every decade promises change, and the first decade of the millennium did not disappoint. The Fall 2010 issue of Gems & Gemology, which mails Oct. 22, looks back on 10 eventful years in the gem and jewelry industry. Building on retrospectives from the Spring 1990 and Winter 2000 issues, this special volume provides an overview of the major developments in marketing and distribution, gem localities, treatments, and analytical techniques.
De Beers’s abandonment of its single-channel distribution role. The rise of online retail. Confronting the issue of “blood” diamonds. These are just a few of the decade’s developments that changed the way diamonds, colored stones, and pearls are bought and sold. Russell Shor and Robert Weldon review the impact of these market forces in the lead article.
Next, Dr. James Shigley and coauthors summarize the new diamond, colored stone, and pearl sources of the 2000s, as well as known localities that remained active. The article includes a stylish wall chart of major world gem-producing regions, a comprehensive table of colored stone localities, and supplemental resources in the online G&G Data Depository.
A decade that began with high-pressure, high-temperature (HPHT) color enhancement of diamonds also witnessed the beryllium diffusion of sapphire and many other challenging and controversial processes. Shane McClure heads a report on the sophisticated new gem treatments of the 2000s and methods of identifying them.
The final article, by Dr. Christopher M. Breeding and coauthors, examines the technological innovations that have shaped gemology in recent years. These include chemical microanalysis techniques, real-time fluorescence and X-ray imaging, and nanoscale analysis.
“These four retrospective articles deliver timely knowledge for every gem and jewelry professional,” said G&G editor-in-chief Alice Keller. “In chronicling the past decade, they offer essential insight on the state of the industry today.”
In addition, a retrospective article on synthetics and simulants will appear in the Winter 2010 issue of G&G.
