Stunning Kanab Goldstone!
This natural sandstone formed 180 to 220 million years ago by wind and water as part of the geological formation "Shinarump Conglomerate". The colours and designs were induced by a mineral spring containing iron oxides.
This particular one is Kanab Goldstone. It is found only in one small deposit near Kanab, Utah. This is 100% natural.
