Lapis Lazuli is a deep blue coloured stone , often exhibiting a suble mottled pattern.
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.
It was prized for its beautiful deep celestial blue colour by many ancient cultures , often being worn by royalty. It has been used to create an ultramarine coloured fabric dye.
A birthstone for Capricorn and Libra. A symbol of honour , wisdom and truth . I may bring harmony and inner tranquility.
