    Corundum cover, by Richard W. Hughes of Lotus Gemology


    Richard W. Hughes  |  1990

    Rubies and sapphires are widely considered to be among the most sought after and precious of gems. Together they account for over fifty percent of the world trade in colored gemstones. This book is the first from Richard Hughes on the subject, and the first major work to be devoted entirely to the corundum family of gemstones. It covers all aspects of rubies and sapphires, beginning with their history, chemical and physical properties. Other chapters look at treatments, synthetic corundums, methods of fashioning, famous rubies and sapphires, formation of corundum deposits and world sources, providing a valuable reference source for jewelers, gemologists, students, and the general reader.

    Inside Out  •  GEM•ology Through Lotus-Colored Glasses

    E. Billie Hughes, Richard W. Hughes, Wimon Manorotkul  |  2020

    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.

    Jade  •  A Gemologist's Guide

    Richard W. Hughes, editor  |  2022

    The study of jade is unlike any other gem, trespassing across all 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 reduction and definition, but an expansion of the mineralogical lexicon to include the cultural aspects of human civilization and life. The word “jade” is the anti-mineral. Because jade is so much more than a simple census of atoms, their valence states, and their places of residence.

    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 in the world of gemstones. It is our heartfelt hope that this volume will not just fill the “traditional gemological” gap, but will open readers’ eyes to a world beyond. Because jade is so much more.

    While the literature on jade is vast, perhaps greater than any other gem, there is a distinct lack of a volume 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 the various forms of imitation jade. All of this is together in a single volume for the first time, making this a must-have for all collectors, dealers, gemologists, appraisers, curators and anyone else with an interest in this fascinating gem.
