Lapis Lazuli Cabochon
Lapis lazuli cabochon with a wonderfully distinctive colour which is one of the reasons why this blue metamorphic rock has been prized by man for thousands of years. Highly polished and included with the mineral iron pyrite, it comes from the Badakhshan province of northeastern Afghanistan.
Lapis lazuli is often referred to as a mineral which is incorrect because it's made up of several different minerals which makes it a rock, not a mineral in its own right. Its blue colour is caused primarily by the mineral lazurite and this well known stone features in many famous artifacts from around the world the best known of which is the death mask of Tutankhamun.
Used by the ancient Egyptians for jewellery, beads and amulets, lapis lazuli was also used to make a pigment called ultramarine which was used extensively in paintings from the Renaissance and Baroque periods.
