Bismuth Rainbow Crystal Staircase - 1.896" 2026Q1-standard-20percent They are roughly 1/2" (2cm)Bismuth 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. 896". While bismuth's practical uses are limited beyond some pharmaceuticals, the element's utterly unique colors and shape continue to
