2000-2010: GIA’s Fall Gems & Gemology Reviews

Decade of Gemological and Industry Developments

CARLSBAD, Calif. – Nov. 2, 2010 – The Fall 2010 issue of Gems & Gemology (G&G), now available, focuses on major industry developments that shaped the millennium’s first decade. This special edition of the quarterly scientific journal, published by the Gemological Institute of America (GIA), features a retrospective on changes in marketing and distribution, gem localities, treatments and analytical techniques.

The lead story, by Russell Shor and Robert Weldon, examines the milestone events that impacted the way diamonds, colored stones and pearls were bought and sold in the past decade. From De Beers’ abandonment of its single-channel distribution role, to the rise of online retail and the controversies surrounding “blood” diamonds, the article covers the most significant industry trends.

Another G&G story, by Dr. James Shigley and coauthors, summarizes the new diamond, colored stone and pearl sources of the millennium, as well as known localities that remain 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.
