The jewellery trade has long put a premium on gems from certain locations, such as blue sapphire from Kashmir or ruby from Myanmar (Burma). Yet other localities produce stones that rival those from these revered sources. Whether it is fair or not, gems from renowned sources command the highest prices. For that reason, determining the geographical origin of a stone can mean the difference of hundreds or even thousands of pounds in value. This month, Shane McClure, Global Director of Coloured Stone Services at GIA, discusses the challenges laboratories face when determining the geographical origin of various coloured stones.
This is the first assignment in the 2020 Continuing Education Recognition Programme. You will have continuous access to the entire course -- including the assignments, the GIA eLearning courses, and the multimedia archive -- until the end of the calendar year. make sure you complete all eight assignments by 31 December 2020 to receive your Continuing Education Recognition Programme certificate.

An essential asset of GIA’s research department is its reference collection of gem samples from around the globe. Used by scientists to gain better a better understanding of the geographical origins and treatments of gems, the collection has been built through the efforts of GIA’s field gemmology department. The field gemmology department was established in 2008 specifically to support GIA research. GIA field gemmologists have conducted more than 95 field expeditions to six continents and collected over 22,000 samples. This month, GIA’s supervisor of field gemmology, Wim Vertriest, discusses GIA’s classification system as well as the challenges of working in the field.

Trapiche gems, often considered beautiful oddities of Mother Nature, are truly treasures for the gem connoisseur. True trapiche consists of gem segments separated by arms formed by inclusions. Trapiche emeralds from the Muzo mine in Colombia were first described by Émile Bertrand in 1879 at a meeting of the Société Géologique de France. Since then, other gems that form as trapiche have been found. This month, Jeffrey Bergman of 8th Dimension Gems discusses his passion for these unique gems and their equally unique place in the market.
Interview: Susan Wheeler
Responsible sourcing has become a hot topic across all aspects of life. More and more, consumers are searching out products that are manufactured in sustainable ways. They want to know if the workers who contribute to the making of those products are treated fairly and how the environment is impacted in the process. A growing number of jewellers are asking these same questions — and, furthermore, looking at ways to give back to the communities they depend on for their raw goods. At the forefront of this wave is Susan Wheeler, a jewellery designer and founder of the Chicago Responsible Jewelry Conference. Join us as Ms Wheeler discusses the challenges and rewards of ethical gem and metals sourcing.
