Lapis Lazuli is not a single mineral. It is a combination of lazurite, calcite, and pyrite, with small amounts of other minerals. Contrary to common belief, it does not contain lazulite. Lapis Lazuli literally means "blue stone" from Latin and Persian or Arabic. Lapis Howlite or blue howlite may look like Lapis Lazuli at a glance but are not the same stone. Denim Lapis is a lighter Lapis Lazuli with more white from calcite.
