The study of jade is unlike that of any other gem, trespassing across conventional boundaries, particularly those of the gemological and mineralogical realm. Despite the march of mineralogical orthodoxy and conformity, the word “jade” is a fist in the air of protest, crying out not for further reduction and definition, but an expansion of the mineralogical canon to include the cultural aspects of human civilization and life. Because jade is so much more than a simple census of atoms, valence states, and places of residence. Jade is a lexicon liberator.

While the literature on jade is vast, perhaps greater than any other gem, there is a distinct lack of a volume in English that treats jade as a gemological material. This book is designed to fill that gap, with extensive information on the history, sources, appraisal and identification of both treated and imitation jades.

An understanding of jade is not limited to the technical or exacting; it also incorporates a feeling for the cultural, textural, and ephemeral qualities that make the study of this gem unlike any other.

A few comments from reviewers…

Voilà un livre de poids, 735 pages et plus de 4 kg qui enrichira vos connaissances historiques comme scientifiques et gemmologiques. L' auteur, bien connu des gemmologues, nous offre un nouveau voyage dans l' univers des corindons. C' est un livre à regarder, approcher, toucher, feuilleter, découvrir enen l' ouvrant avec à la fois impatience et retenue, pour finalement s' y abandonner. C' est une leçon de vie, un livre-compagnon à déguster sans modération.
