The World of Gemstones

Fascinating Diamonds 2: Science and Gemology (4h)

Fascinating Diamond 2: Science and Gemology

Discover why the Diamond is so unique.

The teachers will relate the diamond's history, from when it was first polished in the 4th century BCE to the invention of the modern brilliant cut in 1919, which enabled it to express its full brilliance. 

Discover the secrets of this gemstone: its chemical composition, totally improbable birth, unequaled hardness, the mystery of its brilliance, and its fire.  

Handle stones, classify them by colors and assess their clarity, use gemologist's tools, and look at exclusive documents. 

About the Course

The only gemstone composed of one single chemical element, the diamond hides so many mysteries: the miracle of its birth, its totally improbable meeting up with human beings and the five characteristics which determine its supreme hardness.  

At L'ÉCOLE, School of Jewelry Arts, several courses are entirely dedicated to the Diamond and in order to give a very panoramic view on this "Stone of Stones".

We also offer a shorter version of this course, in 2 hours, focused only on an introduction to the world of diamonds: "The Diamond: A gemological exception". The course "Fascinating Diamonds 2: Science and Gemology" includes the knowledge covered and the experiments made during the 2-hour course; it is therefore not recommended for the same person to do both courses.
