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.

Rutile Silk in Sapphire | Discovery in 1878
In 1878, the noted Austrian mineralogist, Gustav Tschermak von Seysenegg [1836–1927], was the first to properly identify silk in corundum, finding it to be composed of the mineral rutile (TiO2). An English translation of his landmark paper is included, along with the original German version.
