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.
