Richard T. Liddicoat–Mr. GIA

In this episode, Mr. GIA . . .

Can you name one person who, during your lifetime, changed your life in an extraordinary way? Was it a parent, a teacher, a historical figure, or maybe a serendipitous acquaintance? One person stands out among all others - Richard T. Liddicoat. Sunday, March 2, 2025, would have been Mr. Liddicoat’s 107th birthday. Although he passed away in 2002, his memory lives on in me.

In 1985, as a resident student at the Gemological Institute of America (GIA) in Santa Monica, CA, I was invited by Richard T. Liddicoat Jr. (then Chairman of the Board) to his office.

Liddicoat was a student of human nature, a lover of gemstones, and a lifetime GIA advocate. He would visit every Resident (on campus) Colored Stone/Gem Identification classroom just before each class was to graduate. He would often bring samples of remarkable gems submitted to the GIA Gem Trade Laboratory for the students to see. He would also stop by a classroom to discuss industry trends, the latest developments in synthetics, or whatever the hot topic of the day was.

Honestly, I can’t remember what he said the day he visited our classroom because when he asked, “Any questions?” Everyone sat there, blank expressions on their faces, horrified to speak. After all, this was Mr. Liddicoat–who wrote the book on Gemology—a jewelry industry icon—the Father of Modern Gemology, Mr. GIA! Needless to say, our group was somewhat intimidated.

At that time, in addition to the Gem Identification Lab Manual, Liddicoat’s Handbook of Gem Identification (first published in 1947) was provided to each student as a supplementary reference tool for understanding what to look for and the tests necessary to verify the identification of unknown gemstones. My copy was well-thumbed, and I consistently ferreted out identification clues that the "Lab Manual" did not offer.

In the dead silence, my hand shot up enthusiastically, “Mr. Liddicoat, would you sign my copy of your book?” “Absolutely,” He said. “Stop by my office after class.”

So, I did . . .

I’ll never forget what he asked me that day: “What are your plans after graduation? We want you to return as one of our instructors. We're always looking for young people with your enthusiasm.” His uncanny ability to cultivate people was like mining for gems: He always looked for the good in others.

For those of you who knew Mr. Liddicoat–whom many GIA staff affectionately called "RTL"–he was our leader, friend, and patriarch for over 60 years. RTL treated everyone at GIA like his son or daughter. During his visits to the Carlsbad campus long after retirement, he would stroll the halls, greeting students and colleagues by name and taking the time to chat with and encourage each individual.

His accomplishments encompassed many aspects of gemology: Liddicoat created the internationally recognized diamond grading system, expanded GIA’s education programs, elevated the Gem Trade laboratory and research functions, developed instruments to aid gem identification, wrote ground-breaking articles and books, was Editor and Chief of Gems & Gemology, and was the visionary behind the idea of a world-class gemological research library, which now bears his name: The Richard T. Liddicoat Gemological Library and Information Center.

In honor of his birthday, I hope you will take a few minutes to reflect on the values he imbued in you: integrity, respect, empathy, authenticity, and a willingness to go the extra mile for anyone who needs encouragement and direction.

He will always hold a special place in my heart as Mr. GIA, just as he does for millions of students worldwide.

Now, I realize that Mr. Liddicoat was a unique individual among millions. Still, my message is to remember that we encounter remarkable people who influence us and others daily. In our fast-paced world, take the time to appreciate and thank those exceptional individuals who make a difference–you may be one of them!

I'm Patrick Ball. Remember–stay curious and ask questions. See you in the next episode.

We Need Awe More Than Ever

In this episode, Why We Need Awe More Than Ever Yesterday morning, I slipped into the cool stillness of my backyard before dawn. The air was crisp, the silence deep—broken only by the faint rustling of leaves and the familiar calls of birds waking early. Then I looked up. A thin crescent moon hung low in the east, with Venus just above it like a shining jewel. The sky was clear and full of stars, and for a moment, I felt something I hadn’t in a long time: Awe! For thousands of years, the heavens have carried on their steady dance, untouched by human noise. No ruler, no election, no breaking news has ever changed their rhythm. And yet here I was, tempted to reach for my phone—to trade the eternal for the urgent. Instead, I stayed. I watched the moonrise, the sky slowly lighten, and the world around me stir. Ducks passed overhead in a loose V, hummingbirds zipped past to visit their feeder, pausing mid-air as if curious about me sitting so still. Little by little, the static in my mind f...

The Birth of a Cubs Legend

In this episode, The 162-Game Exhale — and the Birth of a Cubs Legend There’s a hush in the baseball world on Game 162 — a collective breath drawn in and slowly released. Scoreboards stop flipping. Dugouts empty. For six months, the game has been our steady heartbeat, pulsing from the cherry blossoms of Tokyo in March to the crisp, playoff-charged winds of late September. And now, as the regular season exhales, baseball fans everywhere pause to absorb the story we’ve just lived. For me, that story has been deeply personal. This season unfolded in the rhythms of my daily life. It was the summer soundtrack echoing beneath the constant turmoil of politics and sensational headlines. It was a handful of carefully chosen ballpark pilgrimages stitched together with countless nights in front of MLB.TV. And at the center of it all, for a lifelong Cubs fan like me, it revolved around one name — a young center fielder who turned hope into history: Pete Crow-Armstrong. The 2025 season didn’t begin...

The Pessimism Aversion Trap

In this episode, The Pessimism Aversion Trap Picture this: a room full of bright minds nodding in agreement as a bold new strategy is unveiled. The slides are polished, the vision is grand, and the future, we're told, has never looked brighter. Everyone beams—because who wants to be the one to say, "Um… this might not work"? Heaven forbid someone spoil the mood with a dose of reality. Better to smile, add a buzzword or two, and march confidently toward disaster. That's how the Pessimism Aversion Trap works. Even now, I can still hear the sound—a high-pitched shriek and a digital hum, followed by the slow, rhythmic clatter of data pouring from a 5¼-inch floppy disk. It was the late 1980s, and my makeshift home office (our living room) was dominated by what felt like a marvel of modern engineering: a used Tandy 1000 PC with not one, but two floppy drives. To top it off, we purchased a 'blisteringly fast' 300-baud modem—which, for the uninitiated, could downloa...

Pushing the Pause Button

In this episode, Pushing the Pause Button: Stepping Off the Treadmill Hello, friends — If you're reading this, I'm already off the grid. Today begins a much-needed vacation, and for the next few weeks, On the Fly is taking a break right along with me. For a long time, my inner voice has said, 'Keep every commitment, no matter what.' That's meant early mornings, long days, and a calendar packed with posts, podcasts, and projects I couldn't seem to say no to. I've been trying to be the tireless workhorse—but that kind of grind doesn't end well. Lately, I've noticed I'm not quite myself—shorter fuse, louder sighs, and a few too many grumbles (Lori deserves a medal). That's when you know it's time to hit pause before the spark burns out. So, I'm stepping back to rest, recharge, and remember what it feels like to not live by the next deadline: no tech, no to-do lists, just some space to breathe. Thank you, truly, for all your support and ...
