Pierres de Caractère: an exploration of Earth's Treasures

“Every stone has a soul of its own,” Claude Arpels used to say.
 
For over a century, exceptional stones – or ‘Pierres de Caractère’ - have been at the centrepiece of Van Cleef & Arpels’ creativity. From diamonds to coloured gems, the Maison seeks excellence but also character, that spiritual quality which awakens the senses and instils a unique emotion. 

Dive into the earth and meet its treasures, discovering the origin and evolution of the ‘big four’ precious stones – emerald, ruby, diamond and sapphire – observed through the eyes of noted jewellery and stones experts Joanna Hardy and Olivier Segura.

Speakers:
Joanna Hardy (Independent Fine Jewellery Specialist)
Olivier Segura (Gemologist and Scientific Director at L’ÉCOLE, School of Jewellery Arts)
