Broken Bangle | The Blunder-Besmirched History of Jade Nomenclature takes readers through the entire tortuous history of jade nomenclature, detailing how the current monikers were based on misinformation and misunderstanding of the gems’ true natures. Thus, the Chinese gem yù (amphibole jade) was named “nephrite” by French mineralogist Alexis Damour in the mistaken belief it was the same as the Mesoamerican pyroxene jade that a 16th Century Spanish doctor himself misinterpreted as being used to treat kidney disease (‘nephritus’). Later, Damour created a mineral species he called “jadeite” for what was actually a gem rock already known in China as fei cui.

But this gemological whodunit is much more than a dry recitation of jade nomenclature. It includes a detailed section on the occurrence and mineralogy of both yù (nephrite) and fei cui. Because jade is so intimately connected with Chinese culture, much of the Middle Kingdom’s fascinating history is also woven through its pages.

Did we mention the illustrations? Broken Bangle features dozens of color images of both historical documents and spectacular photos of contemporary jade and stone carving in China. For those whose mental picture of jade sculpture is a cliché Chinese goddess statue, prepare to have your minds blown.

Lead author Liu Shang-i summed up the book’s major aim:

Our understanding of the world is deeply influenced by the names we assign to things. As history, culture, and scientific inquiry evolve, it becomes essential to assign accurate and fitting names to these unique types of jade that embody Chinese heritage. This nomenclature should reflect its cultural significance and resonate with both historical context and contemporary understanding.

Co-author Zhou Zhengyu added:

There is an ancient saying in China termed “casting a brick to attract jade.” Any book or article is only a stage of understanding, and this understanding, if it can be better than before, is progress. Our work is certainly not the last word on the subject, but we hope it will help improve people’s understanding of this gem’s fascinating history and inspire others to research the subject further. Not unlike a brick thrown in the hopes of attracting jade.

This edition of Broken Bangle is limited to just 600 copies. Don’t miss this chance to enjoy not just superb scholarship, but also extraordinary examples of China’s modern jade culture.
