I had the opportunity to attend an online conference titled “Sapphire: Art & Science”, presented by L’École des Arts Joailliers. Led by Laurent Massi, PhD in Materials Physics and gemologist, and Marie-Laure Cassius-Duranton, art historian and gemologist, the conference was a key moment in deepening my knowledge of this fascinating gemstone.
The conference was divided into three parts. In the first, “What is a Sapphire?”, I learned that sapphire is a variety of corundum, an extremely hard mineral, second only to diamond in terms of hardness. What particularly stood out to me is that sapphires exist in a variety of colors, although blue remains the most iconic.
The second part, “The Color Blue,” focused on the importance of this specific hue, which is the main reason for the popularity of sapphires. I learned that the blue color results from trace amounts of iron and titanium within the corundum. The quality and intensity of this color strongly influence the stone’s value. This analysis further strengthened my admiration for the subtleties and complexity that make each sapphire unique.
Finally, the third part, “A World Tour of Sapphires,” highlighted the main sapphire mining regions, from Myanmar and Sri Lanka to Kashmir and Madagascar. Laurent Massi also shared insights from his professional experience in Thailand, a global center for sapphire cutting and trading, which helped me better understand the economic and cultural dynamics surrounding this precious gemstone.
This conference allowed me to better understand the science behind the beauty of sapphires, while discovering their impact throughout history and in contemporary jewelry. It further strengthened my passion for gemstones and the art of jewelry.
