🧠 Lecture: The Science and Psychology of Gemstones: Diamonds & More

🎤 Speaker: Tristan Griffey-Jones, G.G.

Gemstones are far more than beautiful rocks—they’re the product of extreme geological processes, billions of years of Earth’s history, and centuries of human obsession. In this science-driven (but decidedly not dry) lecture, GIA Graduate Gemologist Tristan Griffey-Jones reveals how gemstones form, how experts identify them, and why ruby and sapphire are actually the same mineral.

You’ll learn the surprising science that separates natural, synthetic, and imitation stones, while dismantling common myths about diamonds and colored gems. Along the way, Tristan will unpack infamous gemstone thefts and scandals, the controversy surrounding laboratory-grown diamonds, and how rarity, provenance, and human psychology shape value just as much as chemistry.

Tristan Griffey-Jones is a Graduate Gemologist from the Gemological Institute of America (GIA), professional jeweler, and gemstone dealer whose work spans the wholesale market and bespoke jewelry design. Blending geology, chemistry, optics, history, and economics with sharp humor, he specializes in demystifying the gemstone industry for curious minds.

Whether you’ve purchased fine jewelry or simply love asking “why?”, you’ll leave seeing gemstones—and value itself—in a whole new light.
