Super White is a quartzite. Quartzite is a metamorphic rock that started out as sandstone. Due to tectonic pressure and massive amounts of heat, the sandstone "melted" and transformed into a very dense, extremely hard stone.

Super White, White Macuaba and Luce di Luna are all white quartzites with grey and limited other colours - lending itself to a marble look, but with none of the etching issues people normally associate with calcium based materials.

Quartzite (on the left) - a natural stone - should not be confused with quartz surfaces (on the right). Quartz, going by trade names such as Cambria, Cesar Stone, Silestone, Quantra and many others, are oatmeal-y looking composites of plastic resins with ground-up bits of glass, shell or rock in there for colour
