Bismuth Rainbow Crystal Staircase - 1.597" britishhistory They are all highly polishedBismuth is an element (Bi 83) best known for its unusual staircase shape, the result of bismuth atoms attaching to the edge of a rapidly growing crystal. This is called hoppering, when atoms are drawn to the edge of a structure, creating a lattice formation. This specimen is a Bismuth Rainbow Crystal, measuring 1. 597". While bismuth's practical uses are limited beyond some pharmaceuticals, the element's utterly unique colors and shape continue to
