Rarely does one encounter an individual who alters the course of history. It is even more rare to know a person of such stature, or to have the chance to work under his or her leadership.

I have been privileged to work for, and alongside, Richard T. Liddicoat throughout my nearly 27 years at GIA. I have seen him, in good times and bad, endure challenges and tribulations, and never falter. I know him to be a man of extreme intelligence, impeccable character, and genuine humility. He is a unique combination of warmth and charm, drive and dedication.

This issue of Gems & Gemology honors Richard Liddicoat’s 50 years as chief editor of the journal. Each paper represents a different aspect of his contribution to gemology. The lead article, by Dona Dirlam and others, gives us a glimpse into his life, his passion, and his accomplishments in an industry he loves and for the public he serves. In honor of his leadership in the field of gemology, researchers at the Smithsonian Institution bestowed the name liddicoatite on a new gem tourmaline species in 1977. The article on liddicoatite in this issue contributes greatly to our understanding of this beautiful but enigmatic gem.

Throughout his career, Richard Liddicoat has focused on gem identification and instruments to make this process easier and more efficient, sharing knowledge that greatly influenced the development of the contemporary field instruments and techniques discussed in Edward Boehm’s piece. But he is also fascinated with the lore of fabulous stones, like the Star of the South diamond described by Christopher Smith and George Bosshart, that have contributed so much to the rich history of our industry.

The issue rounds off with short articles on two topics of particular interest to Richard Liddicoat—pearls and new gem materials. Although a mineralogist by training, he has long had a fondness for organic materials and especially the intricacies of pearls such as the “Tahitian” yellow cultured pearls described by Shane Elen. I wonder, though, if there is a greater thrill for any gemologist than the opportunity to examine a new gem material, as with the serendibites characterized by Dr. Karl Schmetzer and Mr. Liddicoat’s colleague for more than 60 years, Dr. Edward Gübelin, along with other prominent gemologists.

I suppose it would be enough to have established diamond grading and other standards for the gem and jewelry trade, to have educated countless thousands in the field, or to have contributed mightily to the gemological literature over the course of his long and successful career. But perhaps the greatest gift Richard Liddicoat has given us is the example he set for an industry and its professionals. Not only is he a beloved and respected leader, but he also has lived out a work ethic and a commitment to purpose that are both rare and resounding.

As we look back over the years, and his achievements, we recognize that they are unparalleled: a gem mineral named after him; awards and honors from GIA, the American Gem Society, the American Gem Trade Association, and numerous other organizations; and a lasting impact on thousands who revere him as the “Father of Modern Gemology.”

Yet one of Richard Liddicoat’s most appealing qualities is that he has never realized how great he truly is. This issue of Gems & Gemology is a tribute to his character and to what makes him, in my mind and in the minds of all who know him, a man who has altered the course of history in the gem and jewelry world.
