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

Vladyslav Y. Yavorskyy & Richard W. Hughes  |  2010

Terra Spinel takes readers into the world of spinel through the lens and collection of renowned spinel dealer, Vladyslav Yavorskyy. Some of the world's finest spinels are featured in this book's pages as Yavorskyy travels to the most important locations. The traditional sources Burma (Myanmar), Tajikistan, and Sri Lanka are covered in detail, along with newer finds in Vietnam, Tanzania and Madagascar. This is not a gemology book in the traditional scientific sense. Instead, what it represents is a celebration of a rare gem and the places from which it comes. Stunningly illustrated, it is a must-have for any gem lover.

Color types such as "pigeon's blood," "Paraíba" and "cobalt blue" have become wildly popular in the gem trade. But there is a vast difference between coining such terms and applying them in a way that is both consistent and logical. Richard Hughes casts a critical eye on the subject.

Since the late 1960's, East Africa has been home to some of planet earth's greatest gem discoveries. And yet, little has been written about certain of these finds. In the autumn of 2007, the authors set out to fill in the gaps, specifically regarding Tanzania's Mahenge, Songea and Tunduru regions.

Why should Hugh Hefner be the only one to enjoy twins? This special Hyperion Inclusion Gallery features images from the Lotus Gemology Hyperion Inclusion Database, but are shown as pairs, all the better to compare one form of beauty with another.

For those who wish to explore the literature of inclusions in gemstones further, we have selected the following articles and books that are of particular merit. Most of these are cited in the Lotus Gemology Hyperion Inclusion Database, but are listed below in a more convenient summary format. Many of the links will allow you to download a PDF copy of the original article.

Lotus Gemology produces what we feel are the finest gem testing reports in the gemological field. Each report includes gemstone identification, treatment identification and, in certain cases (mainly ruby, sapphire, spinel, emerald and jadeite jade) origin determination.

Lotus Gemology warns that oiled rubies, sapphires and spinels are entering the Bangkok wholesale market in increasing numbers. Most, but not all, of these gems are originating from Burma.

When a red spinel and a tanzanite were submitted for testing, oil was found in the fissures. Removal of the oil resulted in a startling deterioration in clarity.

The author makes his first pilgrimage to Burma's Mogok Stone Tract.

Since the turn of the millennium, the price of fine spinel has risen at an incredible pace. No longer simply the poor man's ruby, spinel is finally getting the attention it deserves as one of the world's premier gems.

To the jeweler, spinel is famous for its vivid colors. But for the gemologist, this gem is unlike any other. Its extreme hardness allows a fine polish. Couple this with single refraction, which eliminates the image blurring found in most other gems, and a varied landscape of inclusion subjects, and the result is an unparalleled canvas of delight for the photomicrographic artist.
