    Inside Out: Gemology Through Lotus-Colored Glasses

    Introducing…

    Inside Out: GEM•ology Through Lotus-Colored Glasses

    by

    E. Billie Hughes  |  Richard W. Hughes  |  Wimon Manorotkul

    with a foreword by Paolo Minieri

    Chinese translation by Jason C.H. Kao (高嘉兴), with Jinding Yu (俞瑾玎) and Bonnie Chao (晁艳)

    From the dawn of time, precious stones have both attracted and fascinated humans in ways that few other items could. For while objects of desire are found throughout the natural world, physical beauty is too often ephemeral. From the allure of a man, woman, flower or butterfly, through the fleeting moments of a sunset, there is little that lasts and practically nothing that can be passed down to our descendants. The exception is precious stones. Not only are they the most durable creations of Mother Nature, but their visual splendor is truly eternal.

    This book presents a completely fresh approach to the subject. Dubbing it humanistic gemology, the authors take readers around the world, showing the places they have explored in their search for gems, along with the people and cultures encountered along the way.

    Within this volume, remarkable photographs of the human world are interwoven with images of the microscopic realm of the gems themselves. In a lifetime beset by time control, where living is broken into ever smaller bits, as you browse through these pages suddenly you plunge into a domain of frozen time, one that affords vistas of millions or even billions of years. For jewels offer not just superficial beauty, but a window on the primordial forces that birthed both our planet and universe.

    Inside Out – Gemology Through Lotus-Colored Glasses represents a fascinating new direction for gemology, linking the external and internal worlds of precious stones for the first time.

    A few comments from reviewers…

    I am doubtless readers both inside and outside of the gem trade will enthusiastically welcome Inside Out. Buy it, read it, give it away. I am fully confident you will be satisfied, ingratiated and inspired.
    Jeffery Bergman – InColor Magazine
    This book fills a gap in the literature on gems by pictorially exploring the relationship between humans and gems on an artistic and emotional level. It is a work of art that lives from the quality of the photographs and gets by with minimal textual commentary on the images.
    Michael Hügi – Journal of Gemmology
    Inside Out is a truly stunning work reflecting the combnied personalities, skills, knowledge and philosophy of the authors, who have created something exceptional and innovative for the world of gemmology.
    Terry Coldham – Australian Gemmologist

    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.
