The most renowned deposit of Lapis Lazuli is that of Sar-e-Sang, in the Kokcha Valley of the remote district of Badakhshan in Northern Afghanistan. Active for over 7000 years, it is the site of some of the most ancient mines in the world. There are certainly other deposits of Lapis Lazuli, but the Afghan variety remains the best by reputation and experience. During antiquity, Afghan Lapis Lazuli was exported along ancient trade routes to Mesopotamia, Egypt, Greece, Rome, India, China and even Japan. The medieval Persian geographer Estakhri visited the Afghani Lapis Lazuli mines in the 10th century and when Marco Polo visited them in the 13th century, he wrote: “There is a mountain in that region where the finest Lapis Lazuli in the world is found."

Due to the many deposits present in Chile, Lapis Lazuli was made the Chilean national stone on 20 September 1984. Other countries where this wonderful gemstone is extracted include Russia (Lake Bajkal), Angola, Myanmar, Canada, Pakistan and the United States.

Lapis Lazuli was mentioned as far back as 2650 B.C. in the famed ‘Epic of Gilgamesh,' the famous poem from Ancient Mesopotamia.

The wonderful blue hue is found, for example, in Persian miniatures from the 13th and 14th centuries, Leonardo Da Vinci’s ‘Last Supper,' and in a miniature in the Church of Saint-Germain d’Auxerre. The color ‘ultramarine’ was highly sought after due to its intensity and resistance to light, and its prices even exceeded that of gold.
