Lazurite is a vibrant blue mineral of the tectosilicates group with the chemical formula Na6Ca2Al6Si6O24S2. It is the blue component in lapis lazuli and is most often found in massive forms, though in some cases it does form individual crystals. Afghanistan is well known for several deposits that produce phenomenal lazurite crystals in a marble matrix. These specimens are highly sought after by both amateur and expert mineral collectors.
