Unmistakable blue lapis lazuli cabochons cut from material mined in Afghanistan.
Highly polished on both sides, these stones exhibit a vitreous lustre which means they reflect light in a similar way to glass.
The blue colour of lapis lazuli has fascinated man for thousands of years. As well as being widely used for decorative purposes in ancient Egypt, it was also ground down to enable it to be used as a cosmetic.
In Medieval times lapis lazuli was used as a pigment in paint particularly by Italian Renaissance artists.
