SEPTEMBER • Art & Science Cycle: The Universe of Gemstones (5 courses)

Diamond, ruby, emerald, sapphire, pearl

Between science, history, and symbolism, gemstones reveal their many facets in five courses.

About the Cycle

In these five classes, discover the composition and creation of gemstones. Handle unique, authentic specimens to learn how to recognize their properties and distinctive features. Explore their history and the meanings they have carried across cultures.

Each session is dedicated to one gem:

  • The diamond will dazzle you with its unique characteristics, its incomparable brilliance, and the role it has played in the societies of Antiquity.
  • The emerald will reveal its characteristic inclusions — known as “jardins” — and its place in the opulent Mughal courts and European treasures.
  • The sapphire, whether in its celestial blue or in its more unexpected hues, will invite you to explore its divine symbolism and the fascination it continues to hold today.
  • The ruby, stone of fire and power, will unveil its secrets along with its scientific specificities, from inclusions to fluorescence.
  • The pearl, a biomineral jewel, will transport you from the depths of the sea to the royal courts, across ancient myths, trade routes, and contemporary cultures.

The classes weave together science, culture, and history, offering a full exploration of gemstones in all their dimensions. The experience includes direct observation and handling of unique specimens from L’ÉCOLE, School of Jewelry Arts' Cabinet.

Please note that the courses are not available for individual booking; a single reservation automatically enrolls you in all 5 sessions.
