- Lapis Lazuli - Lapis lazuli is a semi-precious deep blue coloured stone, sometimes with gold inclusions, that has been used for thousands of years for jewellery, decorative items and decoration.
It is mined in Afghanistan, Siberia, Chile, USA and Burma. The mines in north-eastern Afghanistan are the largest source of lapis lazuli, and have been operating for over 6,000 years.
They were the source of the stone for the ancient Egyptian, Greek and Roman civilsations.
