    Pleochroism in Faceted Gems • An Introduction • Lotus Gemology

    The phenomenon of pleochroism in doubly refractive (DR) gemstones is described, as it relates to overall color appearance in the context of faceted gems. With strongly pleochroic gems, pleochroism can be seen in faceted gems, even if the table facet is oriented perpendicular to an optic axis. This is because facets change the direction of light as it moves through the gem.

    Richard W. Hughes  |  1997

    Ruby & Sapphire is widely acknowledged as one of the finest gemology books ever published.

  • Ruby & Sapphire (Corundum) Inclusions • The Lotus Gemology Crystal Registry

    Corundum Inclusions • A Crystal Registry


    Solid inclusions have been used by gemologists as a means of determining origin. While there is a great deal of overlap from one source to another, there are also important differences. For example, while apatite has been identified in sapphire from Madagascar, Myanmar and Sri Lanka, apatite has never been identified in sapphire from Kashmir. Thus the purpose of this article is to give a full listing of solid inclusions in gem corundums from around the world, with each occurrence fully referenced. This is provided with the goal of making origin determination of ruby and sapphire more accurate.

    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.
