Lapis Lazuli is a deep blue coloured stone , often exhibiting a suble mottled pattern. It is is mixture of the minerals Lazurite, Calcite and Pyrite.
It was formed as the result of contact metamorphism , when pre existing limestone and marble rocks were changed by the intense heat and pressure of intruding magmas. The process formed the deep blue Lazurite stone . Many Lapis Lazuli stones exhibit a speckled gold or silver glint , due to the presence of shiny iron pyrites.
Lapis Lazuli was prized for its beautiful deep celestial blue colour by many ancient cultures and was used to create ultramarine colour fabric dye, favoured by royalty. Leonardo da Vinci and other Masters used Lapis Lazuli to create vibrant blue pigments for their masterpieces.
