Denim Lapis is a rock of multiple minerals. It is named by the beading industry as 'Denim" because it is a lighter color. The blue color is made from Lazurite and also contains more calcite (the white layers or lines) and pyrite (the gold colored spots). Lapis Lazuli may also contain Afghanite, Diopside, Dolomite, Hauynite (rare), Mica, Sodalite, Wollastonite (a white calcium mineral).
Since the main source of Lapis is from Afghanistan if has become rarer and expensive due to the Taliban's activities. They aggressively take over mines and run illegal mines to fund terrorism.
Lapis has also been used as paint pigment (ultramarine). Vincent Van Gogh's 'The Starry Night' contains ultramarine tinted oil paint.
