Leucite – Natural, Rough, White
If exposed to the air and other elements, leucite can pseudomorph (change chemistry without changing shape) into pseudoleucite, a combination of orthoclase feldspar and nepheline. Further exposure can transform it into the clay mineral kaolinite, like these specimens from Brazil. Photo by Eurico Zimbres. Licensed under CC By-SA 2.5.
