Gems & Gemology Spring 2015 Explores a World of Colored Gems

from a press release

Gems & Gemology Explores a World of Colored Gems
Spring 2015 issue reviews Chinese jewelry designers, colored diamond spectra and more


CARLSBAD, Calif. – May 1, 2015 – The first Gems & Gemology (G&G) issue of 2015 takes a journey around the world to review Vietnamese blue spinel, Moroccan amethyst, Mozambique ruby, contemporary Chinese jewelry designs and the Tucson gem shows. The Spring 2015 issue of G&G, GIA’s quarterly professional journal, is now available in print, and online with exclusive video content.

G&G’s cover story is “Blue Spinel from the Luc Yen District of Vietnam” by French researcher Boris Chauvir√© and his coauthors. The article offers geological context and a gemological characterization of the vivid blue spinel found in Luc Yen, northern Vietnam, which owes its remarkable color to traces of cobalt.

Next is “The Chinese Soul in Contemporary Jewelry Design.” GIA’s Andrew Lucas, Merilee Chapin, Moqing Lin and Xiaodan Jia survey the notable progress China’s jewelry designers have made over the last decade. Influenced by their cultural roots and driven by the rapidly growing domestic consumer market, the artistic prowess of Chinese designers is increasingly evident on the global stage.

Another feature by a joint Moroccan-Italian team headed by Fabrizio Troilo provides an introduction to amethysts from Boudi, Morocco. The study outlines the geology, mining, and the internal and external features of this attractive material. The fourth and final peer-reviewed article, by GIA researchers Dr. James Shigley and Dr. Mike Breeding, reviews colored diamond spectra, including an exclusive and informative foldout chart. In a field report, GIA authors Merilee Chapin, Vincent Pardieu and Andrew Lucas report on the geology and mining practices at Mozambique’s Montepuez ruby deposit, currently the world’s most important commercial source of ruby.

The issue also contains in-depth coverage of the February 2015 Tucson Gem and Mineral shows, as well as reports on the recent Gemstone Industry & Laboratory Conference (GILC) and the GIA-sponsored International Diamond School for natural diamond researchers held late January in Brixen, Italy. Additional details about G&G, full articles, more in-depth coverage, hundreds of additional photos, and exclusive video footage are available on GIA’s website at http://www.gia.edu/gia-news-research.
